STOP 0x0000007B Blue Screen Errors

By January 24, 2009

Follow me on:

The most popular Blue Screen of Death error in Windows is the STOP 0x0000007B error, sometimes called the 0x7b error or the "INACCESSIBLE BOOT DEVICE" BSOD.

This BSOD (which is actually the common name for what's called a STOP Error) could mean that there's a serious hardware problem with a hard drive controller, a driver issue, or even a boot sector virus.

See How To Fix STOP 0x0000007B Errors for a complete troubleshooting guide. A common solution to 0x0000007B errors, especially in Windows XP, is to disable AHCI mode (or change it to Legacy, IDE, or whatever the other option is) in your computer's BIOS. However, I highly recommend looking at the complete troubleshooting guide I just linked to so you can work through the problem properly. You don't want to make it worse.

Have you ever seen the STOP 0x0000007B BSOD before?

Had a system32\hal.dll error. Followed your instructions through it and fixed it. Just wanted to say thanks. Your instructions made it simple. Without your directions I wouldn’t have known where to begin. Took about 20 minutes.

hey Tim,
when i want to set up XP in my laptop a blue screen appears and says a problem has been detected and windows has been shut down to prevent damages. and it shows stop error code 0x0000007B (0xF7A8C524, 0×00000034, 0×00000000,0×00000000).

what can u? I need to install XP badly….

November 20, 2009 at 12:08 pm
(5) Tim Fisher says:

@redwan: You need to press F6 when the Windows XP Setup process begins (there’s a prompt at the bottom of the screen so watch for it) and install updated drivers for your hard drive controller. Unfortunately, you’ll HAVE to do that from a floppy disk. In Vista and 7, if you encounter this need, you aren’t restricted to a floppy but you are with Windows XP.

In my case, I have a Win2K VM running in parallels on my Mac (OSX). Was working fine for a long time and then one day I started getting this error. Still have yet to resolve it.

(7) wjk65 says:

I have the same problem as redwan (4)
I cannot get off the bluescreen or the black screen with the various startup modes–none work, so I cannot follow through with the suggestions below.
any help appreciated.thx

(8) Tim Fisher says:

@wjk65: Have you tried reinstalling Windows? What happens during setup?

December 11, 2009 at 4:11 pm
(9) Tim B says:

I also have redwan’s trouble – I’m trying to install XP onto a laptop so that I can use a piece of lab hardware for which there only exists XP drivers. Of course, this being a nice, modern laptop means that there is no floppy drive – is there any other way to get the drivers on? I’m currently trying a BartPE disk, so far same trouble.

December 11, 2009 at 8:42 pm
(10) Tim B says:

My problem is fixed – changed from SATA mode to IDE mode in BIOS, I can now install XP :)

me tim fisher i also have the same problem that blue screen of redwan.. i have installed already new xp but it stil prompting that blue screen help needed

January 12, 2010 at 12:10 pm
(12) Tim Fisher says:

@ace: If you can get to Safe Mode, update the hard drive controller drivers. If not, you’ll need to reinstall Windows.

(13) Jon W says:

I also have this issue, but it’s with an Acer netbook that has a 8gb NAND flash module for the hd. I was sent recovery disks, but it doesn’t recognize the external cd drive when I boot from them. It will begin to boot to a UBCD, but then I get the blue screen. Anyone else run into this on a similar netbook? Not sure what else I can try.

January 12, 2010 at 12:12 pm
(14) Tim Fisher says:

@Jon W: Have you checked the boot order in BIOS? Your problem could be as simple as the netbook looking at the internal flash drive before the USB ports for boot data. Give that a shot first.

January 20, 2010 at 12:52 am

Tim B is rigtht! my problem also solved when I changed to IDE in BIOS!

(16) Cliff says:

Tim,

Your instructions look good, but unfortunately for me, I can’t get to any of the locations to start the process. I start-up, can choose normal or safe-mode, and boom. The Blue Screen of Death. Any suggestions? Only thing I can think of is reinstalling windows.

February 14, 2010 at 5:10 pm
(17) Tim Fisher says:

@Cliff: That’s about you’re left with. Assuming of course you’ve done the hardware stuff like updated BIOS (you can usually do this from a bootable CD), cleared CMOS, checked your hard drive (those are bootable CDs as well), etc.

I am running windows xp. I ran GMR to remove a virus and then the computer crashed. I am getting a blue screen STOP: 0x0000007B message. I can’t run my computer in safe mode or anything. I get the blue screen no matter what I do. I can’t run command promt or anything either. Nothing opens. help?

February 14, 2010 at 5:19 pm
(19) Tim Fisher says:

@Oscar: Get that XP disc out and access Recovery Console. From there you can fixmbr (Step 10 in the linked troubleshooting guide).

(21) Darkwaters says:

CarinaTK:
you can still get all the data off of your computer… use Hirams or windows minixp and you can grab all your information, only the boot area is bad, not the program and data area. Hope that helps.

Second, pull your HD and put it in an external HD case and copy it to another machine via USB… again, you get your data.

(22) Punkie says:

I got same problem, I reinstalld XP, for the sirst time everything worked fine, then I installed some others component, and still fine, then I restarted my computer then XP didnt wanna start, just keep repeating itself.
Again, Tim B is rigtht! my problem also solved when I changed to IDE in BIOS!

I almost gave up, then I found this discussion here. You’ve saved me from frustasion. I was thinking to buy a new PC. But I didnt have to.

February 8, 2010 at 11:08 am
(23) Kim Rowden says:

@CarinaTK:
You don’t mention what you are trying to do. Are you trying to re-install Windows XP? If so – did you check your BIOS settings?

You may need to turn off “SATA” (this controls your Hard Drive) and switch the older “IDE” mode. Sometimes SATA is shown as “AHCI” and IDE is shown as “Compatibility”. Switch back to IDE (aka Compatibility) then install Windows XP.

When you are done (re)installing Windows you should shutdown the machine, reboot and go back into the BIOS to re-enable the AHCI setting.

To get to the BIOS setup screen on your PC:
http://michaelstevenstech.com/bios_manufacturer.htm
Dell typically uses F2, IBM uses F1
- look for the “storage” option

It would be helpful if Tim Fisher added something to this effect to his explanation of the causes of the “0xC0000034″ error (in the second place after the 0x7B stop code). It’s pretty common on newer machines when re-loading Windows.

February 24, 2010 at 7:57 am
(28) Tim Fisher says:

@Kattaun: I’m wondering if maybe your laptop isn’t even booting to the CD. If you remove the Knopix CD, does everything appear to act EXACTLY the same way or do you get different screens/errors?

(29) Yvan Novoa says:

Ok, so here’s what happened to my pc. I wanted to do a reinstall after my pc got really really slow. I suspected it was a virus slowing down my cpu, cuz every time i wanted to turn on my pc, there was this process which took la long time to boot. Well, long story short, I did my reinstall, but every time the files were loaded(after putting my xp cd into the tray), just after the “Windows is starting the installation” message, there was this damn BSOD saying I had to check for a virus, if not, check my hard drive for corrupted sectors. (0x0000007b). I did everything tosolve it: change ram, format my hdd externally, and many many more. But my solution was on the dvd rom. It was my dvd which was conflicting with some really bad thing inside (which i still don’t know). So what I did was to borrow my sister’s external cd-rom, change the boot in BIOS, and restarted from it. Everything is really great so far. No problem at all! I highly suggest you try to the same process.

I had the exact same error code as #4 after i flashed my BIOS on my AM2+ board.

When the BIOS got flashed, it defaulted to ACHI Mode under the Sata preferences, Just changed it back to Sata mode instead of RAID or ACHI and it booted just like normal.

To fix this problem i had to boot from XP cd and go into recovery console. Then copy the ATAPI.SY_ to C:\windows\system32\drivers and then type RENAME ATAPI_SY ATAPI.SYS

(34) Gerald says:

Hello Tim
Long story short, i tried to change the antivirus software on an infected pc, rebooted and crashed. Ran recovery console but it didnt recognize the CD unit so i put the HDD into another laptop and then copied winlogon.exe (which was the first fatal crash cause) but still nothing, then i ran the repair for windows XP with the cd and i got a 0x0000007E error, then i put the HDD back to the original laptop and got a STOP 0x0000007B (0xF896663C, 0XC0000034, 0X00000000, 0X00000000) Error. Im clueless as to what i have to not to lose my information and i dont want to mess this up even more. Thx in advance

April 26, 2010 at 9:58 am
(35) Tim Fisher says:

@Gerald: The reason you’re seeing the 0x0000007B error right now is exactly because you ran the repair for Windows XP on the OTHER computer. During that repair, the drivers for the hard drive controller that exists on that OTHER motherboard were installed. Now that the hard drive is in your computer, Windows is generating the 0x0000007B (x,0XC0000034,x,x) error, indicating that the hard drive controller drivers installed are not correct.

I know, I know.

The solution would be to run the repair install again from your original computer, which I know you can’t do because the CD doesn’t recognize the disc. That problem is what you need to be addressing – is the disc dirty? is there a problem with the drive? etc.

(36) Brad Hunt says:

Ok, so here is a real challenge for you. This is my BSOD error:

0x0000007B, 0xBA4C3524, 0xC0000034. 0c00000000, 0,00000000

I am not trying to install windows XP, it was/is still on my pc, I was plagued earliar in the week with rogue anty spywares, but cleared them up. I came home from work the other night and found a new one that was cleverly disguised as one of my regular pc programs, and it fooled me. So I after telling it to clear all the infections, my PC froze. I promptly rebooted and got the a fore mentioned stop error.

At first I could get into the menu to choose safe mode but it still would not let windows open with that, I tried to fix my OS errors with the XP disk that came with my computer, no effect. Now it won’t even let me get to the BIOS or boot menu or anything. I get the Dell logo than BSOD.

So I am hoping for a fix that will allow me to do so with out being able to get into anything. I would rather not have to pay for a new hard drive or PC.

Any help would be appreciated. I am running an Dell XPS400.

April 26, 2010 at 10:01 am
(37) Tim Fisher says:

@Brad: Are you sure you can’t access BIOS or the boot menu? The regular hot-keys don’t work? (i.e. ESC, DEL, etc.). Nothing that happened so far to your computer (that you described here anyway) should have any effect on your ability to get into BIOS or change the boot order.

Your quickest solution would be remove your hard drive, install it in an enclosure (around $20 online), and then borrow a friend’s computer to remove your important stuff and stick it on a DVD or something like that. Then return your hard drive to your computer and do a clean install of XP – which you should have no problem completing assuming you can figure out that ‘can’t get to BIOS’ thing.

I had the same problem with a Dell Optiplex 755. I received the
STOP 0x0000007B(0xF78DA63C,0×0000034,0X x0000000,0×0000000 error message if I booted with Windows XP. I resolved the issue by the following actions

1. On start up (Dell logo), press F2 to enter BIOS

2. Expand the “Drives” section

3. Go to “SATA Operation”

4. Change this from “RAID Auto/AHCI” to “RAID Auto/ATA”

I had this doing a fresh install of XP to a pre-used hard drive. There was an unknown boot sector or partition table or something. So I booted knoppix and did a
dd if=/dev/zero of=/dev/hda bs=1k count=1k
which cleared it all out.

Could have also run a disk wiper like DBAN or similar.

I tried to again format the pc but i failed. This message occurred while formatting is at the position after collecting all driver and just before we get information about our drives in hard drive actually i forgot that step(setup configuring….)something. What should I do? Please help.

Hello, I am putting a computer together for my girlfriend and i am getting the STOP: 0x0000007B error when i boot up. I am using a core i5 750 cpu, EVGA H55 mobo,4 gig Kingston Hyper-X RAM, and a Sapphire Radeon HD 4670 video card. As far as an HD and CD drive im using ones from her old pc which do work because i have taken them out and put them in the old pc again. I have read and i think the problem is that i have the old drivers and whatnot on the HD but my MAIN problem is i cant find out how to boot from a CD on the BIOS. On my computer (running a core i7 920 with EVGA X58 Classified) I can easily find where it is. Please help im at a dead end…

August 7, 2010 at 10:01 am
(50) Tim Fisher says:

@ChadKP: I just looked in the EVGA H55 manual and it says that the boot order options can be configured from the “Boot Device Priority” settings which are located under the main option in BIOS called “Boot Configuration Features”. That’s where you should be able to set CD-first booting.

(51) David K says:

Hi Tim F,

I’m not sure how do I turn off SATA and switch to IDE on my BIOS because the closest one i’ve been is to disable SATA Controller which made my computer hang at the startup screen (where it says acer, and press f12 to see boot menu & del to enter BIOS). My Motherboard model is Acer MMCP73VEM, well at least that what it says on Everest.

Help please? Thanks

August 8, 2010 at 9:51 am
(52) Tim Fisher says:

@David: No, you certainly don’t want to disable your SATA controller. This seems to be a hard step because every BIOS manufacturer has called this option something different. What’s the actual computer model? If I can dig up the manual then I’m sure we can figure this out.

August 8, 2010 at 11:04 am
(53) Chadkp says:

I went into my BIOS and made my HD my second boot and my cd drive the first boot and when i did that all i got is a blinking underscore in the top left corner of my monitor. please help lol…computer make me angry…

August 9, 2010 at 8:59 am
(54) Tim Fisher says:

@Chadkp: It sounds like your computer is having problems booting from the Window disc. Are you install Windows 7, Vista, or XP? Is the disk in the drive and clean? Are you sure the CD/DVD drive works OK?

August 10, 2010 at 5:57 am
(55) David K says:

Hi again, my computer model is an Acer Aspire M1800. It doesn’t include XP drivers on their website, I have some unofficial drivers, but I doubt that’s the case.

August 10, 2010 at 10:47 am
(56) Tim Fisher says:

@David K: The Acer Aspire M1800 manual was worthless as far as BIOS information goes. That’s pretty typical for manuals for full computer systems. Motherboard specific manuals are better but you don’t get those with computer system manufacturers.

It’s also possible that your computer doesn’t use SATA based hard drives so this line of troubleshooting would be useless.

August 11, 2010 at 8:43 am
(57) David K says:

Guess I’ll ask the technician from the shop where I got my computer from then. If nothing can be done I guess I’ll have to live with Vista. Thank you for your help, Tim!

I am trying to load XP pro on a dell inspiron mini 1012. It came preloaded with xp, I am using an external cd drive and am getting the stop error. I have no floppy. is there anything else i can do to get this error fixed. help is appreciated thanks!

September 5, 2010 at 11:44 am
(62) Tim Fisher says:

@Justin: I’m guessing you’re loading XP from a CD that didn’t come with that computer? If so, it’s because the computer needs a special driver for the Windows XP setup process to see the hard drive. That happens FREQUENTLY when using relatively older operating systems on relatively newer hardware.

Normally what you’d do is hit F6 here in the Windows XP setup process and then load from a floppy the hard drive controller driver for your computer. Since you don’t have a floppy, you can’t do that.

Your options: 1) Get a USB floppy drive and hope that BIOS treats it like a real floppy drive so Windows XP Setup sees it as such. 2) Slipstream Service Pack 3 into the Windows XP setup disc and hope that the updated setup process includes appropriately updated drivers so you don’t run into this problem. This may not work and is certainly more difficult than trying #1.

I keep getting this error STOP: 0x0000007B (0xF7906524, 0xC000000E, 0×00000000,0×0000000)

It started after i downloaded avast antivirus and was then asked to delete some infected folders. I don’t have any of the XP cds either so i can’t reinstall. Help me please, im a complete pc novice. Thank you

(78) Tim Fisher says:

@esco910: Try hitting F8 just as, or just prior to, the Windows logo appearing, assuming you can do that. You’ll enter the Advanced Boot Options menu. Once there, choose the Last Known Good Configuration option and see if Windows will boot that way.

I read in many places that sata should be changed to IDE. But my bios was showing IDE only. Here i read that IDE could be referred to as Compatibility mode. And when i changed to compatibility mode, it worked. Thank you.

got this error on Dell Dimension E510 with RAID1 disks. Unplugged disk 1 (i.e. the second one), and it booted into Windows. Re-plugged disk 1 while Windows was running and rebooted. Works! I noticed it copied a file as Windows opened up to desktop. I also changed BIOS RAID setting from “auto” to “RAID On” – but I doubt that was it.

Hi Ive got the same error STOP 0x0000007B, and the thing is that I am using MSI x320 notebook and I am trying to install XP from bootable usb, everything is fine until it tries to start the installation and i get the blue screen with this error. In BIOS I see that my hard dire is SATA but there is no option for changing it. I already checked the troubleshooting page but no luck so far. If you can give me any idea how can I fix this issue it will be highly appreciated !

Thanks

April 3, 2011 at 9:12 pm
(83) Tim Fisher says:

@ivo: You might be out of luck. You’re working with variables that simply didn’t exist when Windows XP was programmed (bootable USB commonplace, SATA drives). Another idea might be to install Windows XP from the USB drive where SP2 or SP3 is slipstreamed in.

i have windows 7 installed in my pc and it worked fine…but now when i switch on my pc it does not load and a blue screen error message appears showing 0×0000007B (0x80786B58, 0xC0000034, 0×00000000,0×0000000)..i tried reinstalling windows7 but then the hard drive is not being recognized.. i tried mini xp but hard disk still unavailable…
is my hard disk damaged or is it some boot virus

April 17, 2011 at 7:43 pm
(85) Tim Fisher says:

@anup: Very hard to say. I’m leaning toward a damaged disk since you also couldn’t see it from the bootable OS – unless of course the MiniXP disc you used didn’t have the right drivers. Have you tried booting to the Windows 7 disc and trying a Startup Repair?

June 13, 2011 at 6:40 pm
(91) Tim Fisher says:

@Muhamamd Asad Fareed: When you changed your CMOS battery, BIOS returned to factor default settings. The default setting for your hard drive must have changed back to the default, which obviously isn’t what you want.

Thanks for this! Been tearing my hair out wondering why a UBCD4Win (which works with all my other PCs) fails on a new Win7 laptop, giving a BSOD STOP 0x7B immediately after the WinXP startup screen appears. Changing the SATA mode in BIOS to IDE cured it!

Hey guys, I seem to have this problem in XP. The BSOD tells me I have STOP: 0x0000007B (0xF789E524, 0xc0000034, 0×00000000, 0×00000000). The PC doesn’t have a floppy disk drive, in addition I looked at re-installing windows, I can see my C drive is nearly empty, which secs before this problem was nearly full. It says the drive is corrupt and needs to be reformatted before I could reinstall. Is there a way to get my stuff back off the drive, then fix this? Any help would be much appreciated.

July 12, 2011 at 4:49 pm
(98) Tim Fisher says:

@Mark HP: Your best bet in this case is to remove the hard drive, put it in an enclosure, and hook it up to another computer and see if there’s anything retrievable. After you’ve done that (or tried that) then stick it back in and format it. Be sure to run a good hard drive test on it as well because if there’s now something physically wrong with it, you may not be able to install Windows. Even if you could, if it’s dying, you could be setting yourself up for this whole scenario again.

July 12, 2011 at 5:19 pm
(99) Mark HP says:

@ Tim Fisher: Thanks for the speedy reply! We only have one other computer in the house which is a Mac, would this cause any problems? Also I have never swapped a drive out before, would I just place in the enclosure and plug it in, or would there be other steps before it would work? I assume I can do the hard drive test with chkdsk? Thanks again for your help!

July 12, 2011 at 5:30 pm
(100) Tim Fisher says:

@Mark HP: I don’t think any other computer would have been involved in this sort of issue. It’s probably just a hard drive that failed before its time (or maybe it’s an older hard drive?). Yes, just place it in the enclosure as the directions say to do so (usually just an easy data and power connection) and the plug it in the USB port of the other computer and take a look. Any major electronics store should have several enclosures to choose from. A chkdsk test is OK but the best option would be something like Seatools for DOS – you burn a disc and boot to it and it’s pretty much automatic. Much more thorough than chkdsk.

I got the BSOD repeatedly after going into sleep mode. The computer would not boot into safe mode or boot from CD. After reading this page, I turned off “RAID” mode on my SATA controller and now I am installing WinXP on a clean drive. Once I have this installed, I’m hoping to reconnect my RAID HDDs to move data over to the new HDD. Hopefully it won’t crash when I turn the controller back on!!

October 2, 2011 at 6:06 pm
(108) Tim Fisher says:

@Muz: This is due to the fact that you installed Windows on the other computer. This issue is appearing because the wrong hard drive controller drivers are installed – the one that work with the other notebook, not the computer you have the hard drive in now. You could try running a Repair Install and see if that’ll clear it up.

Ok, I have recently procured an Acer 6530 Series Laptop from my sister. It says Vista installed on the outer sticker, but they upgraded to Windows 7 before I took posession. My wife and I prefer Windows XP. I happen to have XP on my desktop(professional) and the recovery disk for it. I also have a copy of the XP home edition install disk. In my simpleton moronicness I used the recovery disk on the laptop. After the reformatting began, something went wrong and I was forced to hard reboot the laptop. Now, the OS(Windows 7) is gone and I cant install anything due to the Stop: 0x00000007b (0xF78E2640, 0xC0000034, 0×0, 0×0) Error message I’m getting.I cant run safe mode cause there is NO os, But I can still get to the Boot menu. Any thoughts?

More info on my problem. I found that if exclude the IDE 0: Hitachi HTS543225L9A300-(S from the BOOT order I can start to Install XP Home.

October 14, 2011 at 11:20 am
(113) Tim Fisher says:

@Chris Colossus: That all makes sense. The computer was manufactured post-Windows XP so they didn’t [need to] take in to consideration any issues that might arise by installing an older operating system. No one figured how much people would love their Windows XP and hate Windows Vista. This is a common problem. What you might try is seeing if there’s a legacy mode in the hard drive controller options in BIOS (see step 8). If there is, try turning that on and then attempting the XP install.

Error: 0xoooooo7B (0xF890E524,0xcooooo34,0×00000000,0×00000000)

Other symptom: the PC (no battery installed) is powered on automatically once the power supply is plugged in without pressing the power key.

I also tried to reinstall the XP operating system, but it didn’t work.

October 18, 2011 at 4:33 pm
(115) Tim Fisher says:

@Mandy: Have you tried pulling out the hard drive and then reinserting it? Did anything else happen around the time this started?

October 18, 2011 at 4:40 pm
(116) Mandy says:

No. I thought about pulling out the hard drive, but don’t know how to do and fear it may make the situation worse. The laptop behaved very normally the last time when it was working, though I did notice that it had been slowing down a lot during the last two months. Then it suddenly broke down and gave me the blue screen two days ago.

October 18, 2011 at 4:51 pm
(117) Tim Fisher says:

@Mandy: Don’t fear it. Just find where the hard drive is installed (usually noted with a cylinder icon), remove the screw, and remove and then reinsert the hard drive. All with the laptop removed from power (battery and wall) of course. Some laptops have the hard drives on the side, which are easier to remove, but most these days are under screw and case and accessible from the bottom.

October 18, 2011 at 5:00 pm
(118) Mandy says:

Tim, thanks for your prompt response and detailed instructions. I’ll try reinserting the drive and let you know how it goes. ; )

October 18, 2011 at 5:27 pm
(119) Tim Fisher says:

@Mandy: No problem… let me know how it goes.

October 18, 2011 at 6:13 pm
(120) Mandy says:

Tim, I removed the hard drive, did some careful cleaning, and put it back in. The blue screen is still here, with the same error message asking me to check the hard drive to make sure it’s properly configured and terminated. But the error code changed slightly into:
0xoooooo7B (0xF8A8E524,0xcooooo34,0×00000000,0×00000000)

Is my hard drive broken? How can I test if it’s workable?

October 19, 2011 at 2:52 pm
(121) Tim Fisher says:

@Mandy: The main STOP code (0x0000007B) is still the same. Most of the other numbers are expected to change from BSOD to BSOD. No, I don’t think your hard drive is broken. It could be, but I doubt it. The linked troubleshooting guide in the blog post is your best bet – just walk through what you can. You’re on a laptop, making your job harder, but you should see what you can accomplish. Chances are, you’re dealing with a driver issue – the driver for your hard drive controller, an important one. Repairing your Windows installation is a likely fix (what version of Windows do you have?)

October 21, 2011 at 12:13 pm
(122) Mandy says:

Tim! First, good news: my hard drive proves workable and I pulled out all my files though the laptop is still not working. I don’t think it’s a software problem, because I tried reinstalling the system and ran disk check and nothing happened.

I put the hard drive in an enclosure and connected it to another computer. The hard drive is working perfectly and I backed up everything. I suspect that there’s probably something wrong with the motherboard because it powers on by itself once the power cord is plugged in, but I need to go through the normal procedure — hitting the power key to get it started, if I use a battery as its power supply instead of a power cord. Do you think a motherboard failure might be a possibility?

Thank you so much for assuring me that the hard drive is likely fine. It really pushed me to try the enclosure “method”. ; )

October 23, 2011 at 8:48 pm
(123) Tim Fisher says:

@Mandy: That’s great about the data… that’s the most important part, of course! As to your other question, yes, that’s certainly possible. Of course that’s easy to say because most of a laptop is a motherboard. There’s very little else (aside from RAM or CPU) that’s independent. I’d recommend getting service on it.

October 23, 2011 at 8:50 pm
(125) Tim Fisher says:

@jone: That’s one possible solution, which does tend to work for many. However, if the 0x7B BSOD is caused by another type of issue, that won’t work. Thus the need for a troubleshooting guide.

(127) Tim Fisher says:

@ajay reddy: Are you sure it’s the 0x0000007B BSOD? You say “some error message” – so I just wanted to make sure we’re working with the best information. Assuming that it is, you should check BIOS for a “compatibility” setting – somewhere around the hard drive information, though probably not on the same screen where the hard drive is setup. Did this laptop have XP on it originally or did it have Vista or 7 from the factory?

November 22, 2011 at 4:41 pm
(135) Tim Fisher says:

@himani: The deleted partition should show up as “unpartitioned space”. That 94MB “unknown” is a partition created when Windows 7 was installed. When you delete that as well (this all assuming you’re doing a clean install of XP, right?) you should then have all of your hard drive’s space showing up as “unpartitioned space”.

Hi to every one
before few months ago my laptop crashes, first it was a blue screen after that even no image
So i took it to the service for repair they said that thera was a short circuit and that they have to replace some chip as i understand a controller of something
before I take it for repair I bought a new wd scorpion blue 500GB hard disk formated id and partition whit external usb and the put it on the crashed laptop (compaq presario cq60)
and try it to install a fresh copy of windows XP -no succses
anyway when everything was done and i get back to the shop the said that the old disk is broken and probably the new one too because they can not instal windows on it they show to me that is working with another hard drive that loads windows great
when I get home and put that WD 500G hard drive on the usb it was working just fine i can transfer data and everything the S.M.A.R.T. status was unavailable maybe caused by the usb anyway
I plug the drive on the repaired laptop set the bios to boot from cd and when i start it and when it shows “press any key to boot from cd” and i do so its thinking about a minute or two and then shows the blue screen with error 0x0000007b
i have been trying a lot of software to format and so on and so on but still that blue screen
The BIOS of the laptop is very simple it doesnt show any options to change from SATA TO IDE
after replacing that chip there is no serial number anymore for the system can be that the problem ???

(140) Buko says:

Three dead Vista laptops. Trying to put together one working one.

Took each hard drive out, put in an enclosure to back up some files onto a working machine. So data is not an issue. I formatted each drive. One died (I knew it was on its way out). Ignore that one. Another had a TrueCrypt encryption on it so I don’t even know if formatting did any good. Ignore this too.

That leaves the one formatted SATA drive with two partitions from an Asus.

I put this in the HP laptop I am trying to rescue but we have no recovery/OS disks for Vista. We do have a Windows XP CD. My plan was to put the formatted blank drive from the Asus into the HP, boot from the XP CD and start from a fresh installation of XP. Might be a backward step but I just need a basic Windows machine for going online & DVD creation.

I get as far as booting from the CD, Windows setup seems to start and then suddenly just as it says setup is starting I get the BSOD saying there is a problem and the process has been shut down to protect the computer.

STOP: 0×00000007b (0xF78D663C, 0xC0000034, 0×00000000, 0×00000000)

I can’t do the IDE/SATA thing in BIOS. My BIOS seems to be rubbish and does not give any choices apart from data/time/password settings! When did BIOS stop being useful??

I can’t update any controller drivers etc, there is nothing on the hard drive, no Windows, no safe mode or recovery options.

I just assumed I could put in a blank drive from one laptop to another and start fresh but apparently not. Is this something I just can’t do? Somehow the machine knows it has a drive from another or are there other issues with it? The machine I am trying to save is the one that killed the initial drive so maybe I am thinking there is a bigger issue with it?

Can OEM hardware not be swapped? Would purchasing W7 fix it? Maybe it’s all a lost cause and better to go out and get a new cheap machine.

I miss messing with jumpers and proper BIOS settings.

Thanks for your time.

December 19, 2011 at 11:44 am
(141) Tim Fisher says:

@Buko: What you’re trying to do should be possible. When you say you “can’t update any controller drivers” because Windows istn’ even installed, you’re actually wrong. You CAN and NEED to update the controller drivers that the Windows XP setup program is using. You do this by pressing F6 when the XP setup starts (you’ll see it at the bottom – here). Then you have to use a floppy disk to load the drivers (I know, I know). The problem is that you’re trying to install an old OS on a new computer. The laptop was intended to have Vista or later on it. The hardware maker did not anticipate someone wanting to put XP on it (no one knew Vista would be so bad). So yes, Windows 7 would fix this problem – I doubt you’d have issues. There may be a hardware issue but right now it looks likes a simple XP-isn’t-right-for-this-PC problem. Again, you could load the hard drive controller drivers during setup but if this doesn’t work, I’d go with Windows 7.

January 5, 2012 at 12:55 pm
(143) Tim Fisher says:

@Tassu: Most 0x0000007B issues with new installs are due to Windows Setup having an issue with the hard drive controller driver. I haven’t installed 2003 in several years so I don’t recall the specifics of the setup routine, but I’m guessing there’s an option of adding your own controller drivers during install. Have you looked in to that?

Dear Fisher,

i’m trying to reformat my computer through the boot menu because when i try to do so through the standard desktop, it rejects the version because it is older than the one already installed.

the problem is this, midway through the “processes”, the blue screen of death keeps appearing,

STOP : 0x0000007E (0xC0000005, 0xF786B0BF, 0XF7CB7208, 0XF7CB6F08)

Please help, much appreciated!

February 18, 2012 at 4:09 pm
(150) Tim Fisher says:

@John: Try this search: http://www.google.com/search?q=0x0000007e. Your STOP code is 0x7e, not 0x7b which is what this blog and the linked troubleshooting information refers to.

I had the same problem with a Dell Optiplex 330. I received the
STOP 0x0000007B(0xF78DA63C,0×0000034,0X x0000000,0×0000000 error message if I booted with Windows XP. I resolved the issue by the following actions

1. On start up (Dell logo), press F2 to enter BIOS

2. Expand the “Drives” section

3. Go to “SATA Operation”

4. Change this from “RAID Auto/AHCI” to “RAID Auto/ATA”

(155) alex says:

Hello I had the same problem. My laptop has received a shock and then i got the 0x7b stop error.
I have changed to IDE and then I was able to reinstal windows. The thing is that I didn’t want to reinstall other os, I just wanted to reinstall over the old version, but in the final I have a new os.
Then I got back to try acces Recovery Console like in the tutorial but I don’t have an option to pres R to enter to Recovery Console. I only have D for Delete, Enter or F3 to exit.

After all, I have a new version of Windows but I don’t have anu drivers for it, and all of my data and files are stuck in the other version and project not saved also.

What can I do to regain the control of my old OS?

Thanks alot!

April 10, 2012 at 11:55 am
(156) Tim Fisher says:

@alex: It sounds like you did a “parallel” install. You should look around your hard drive for a Windows.OLD folder that should contain all of your old data. Your programs are lost – you’ll need to reinstall them. However, it’s also possible you did a “clean install” which involved formatting your hard drive (erasing everything) and reinstalling Windows from scratch. In that case, nothing is left.

April 15, 2012 at 7:47 pm
(157) Don says:

I get the 0x0000007b BSOD and I have an HP 8560w laptop. I read all the different fixes and changing to IDE did not help. The challenge is that the disk in encrypted so I can’t boot to anything else and do anything with that drive (unless someone can tell me how). It asks me to load drivers since my OS is not listed. Does anyone know what “setup info” file I may need? I have clicked on a bunch of different ones but it keeps saying it does not include the correct info. Will it be a system file type file versus a dll?
Thanks.

April 30, 2012 at 5:26 pm
(158) Tim Fisher says:

@Don: What you need are the hard drive controller drivers for whatever hard drive controller is in use in your laptop. Your drivers disc from HP or maybe the HP website will have this. It’s not a DLL, it’ll probably be an INI file which contains information about the drivers needed, which will be included in the same folder.

(159) Amer says:

I have a Sony Vaio running windows 7, When I restart Laptop I get the option of (Launch start up repair) or (Starting windows normally) with Launch start up repair It goes through the steps of booting then it gives me a black screen and all I can see is the mouse arrow, with Start windows normally it tries to start windows but then just keeps on rebooting.
Since its a SONY Vaio BIOS is very limited and you can not switch from SATA to IDE. Safe Mode also keeps on rebooting system. I can not gat a CMD prompt. Last Known good config also causes the laptop to keep on rebooting.
If I go and try to install XP on the Laptop I get (0x0000007b)

April 30, 2012 at 5:28 pm
(160) Tim Fisher says:

@Amer: It’s no surprise you get the 0x7b issue when installing XP on this laptop. The hardware was designed to work with Windows 7 and later, though I’m guessing Vista would work fine. It’s not made to work with a much older OS like XP.

June 5, 2012 at 11:54 am
(165) Tim Fisher says:

@Dia: Most laptops that don’t have optical drives (almost all of them these days) have a push-button recovery process that reinstalls the OS. It’s usually activated by a hotkey (like F10, F5, etc.) as soon as the laptop powers on. Do you see that? (not “setup” or “BIOS”, but something else). Also – what version of Windows are we talking about?

(169) Tony94 says:

My computer had recently caught a root virus, so I had to download Windows Defender Offline which requires me to download it to a usb and boot it up from there. So after changing my computer to restart from the usb, the Windows Defender Online scanned and removed the virus. However now I can’t even start the computer in safe mode without it giving me the blue screen. I’ve already loaded back all the defaults for the boot order, restored the pc and even used the start up recovery. Nothings working, and it doesn’t give me the option to change from SATA or whatever it was. I have a Windows 7 dell inspiron. Please help!

July 6, 2012 at 4:15 pm
(170) Tim Fisher says:

@Tony94: You shouldn’t have to worry about the SATA thing if you have Windows 7. That typically only works with Windows XP computers.

You say you’ve used “the start up recovery” – was that the real Windows “Startup Repair” or some sort of Dell utility?

Changing SATA to IDE works fine on my netbook but when i turned back the SATA on the BSOD are still there and still keeps rebooting. What now?

July 20, 2012 at 1:14 pm
(172) Tim Fisher says:

@maverick: Try updating the hardware controller drivers in Device Manager. Your netbook maker’s site should have them. Then you should be able to change back to SATA mode and things should be OK.

(173) David Nelson says:

I have an IBM PC with a DiamondMax 9 Plus (Maxtor 6Y080L0). I tried to swap it to a newer INTEL motherboard but when it booted, I got a blue screen with STOP 0000007B (INACCESSIBLE BOOT DEVICE) and could not even boot in safe mode. I understand that the disc may have IBM-specific firmware which is not recognized by the BIOS. I reinstalled it as a slave drive and it is recognized with all data. However, I would prefer to boot from it if the STOP error can be resolved.

August 13, 2012 at 11:04 am
(174) Tim Fisher says:

@David Nelson: A 0x7B error is so common on motherboard swaps that it’s almost guaranteed. This is due to the fact that the driver that Windows has installed for the hard drive controller integrated into Motherboard A is suddenly at a loss on how to operate once the completely different hard drive controller integrated into Motherboard B enters the picture.

You almost always have to clean install Windows after a motherboard swap (different models… if it was the same make/model then you’d be fine… you might even be fine if it’s the same make but a slightly different model).

Hey guys, I have an old CCE WIN BPS Notebook and i’m having problem with installing windows xp on it. When i’m trying to boot the instalation CD that error appears (0x0000007B).
There’s no option at BIOS to change for IDE or enable C3 configs.
What should i do? Is there another way?

December 21, 2012 at 12:48 pm
(182) Tim Fisher says:

@Eduardo: In you case, I’d guess that the hard drive controller drivers included with the Windows XP setup disc have an issue with your actual hard drive controller driver. I’d search for your old driver disc (or online) for controller drivers and try to slipstream them in during setup.

I can’t seem to figure out how to change to IDE mode, can some one please help with a step by step guide on this?

February 8, 2013 at 11:39 am
(185) Tim Fisher says:

@Dan: It seems every BIOS is different… you can either continue to dig around until you find it or you can download the manual for your notebook and see if it has detailed BIOS information, which it may not have. Also, your computer may not have an option to change this mode. If not, you’ll have to skip this troubleshooting step and move on to another.

March 15, 2013 at 10:11 am
(192) Tim Fisher says:

@Muhammad Naweed A Soomro: The troubleshooting guide I linked to above should help you solve the problem. Just work through it one step at a time. Specifically, if you’re trying to install a very old OS (like Windows XP) on a newer computer, you will almost certainly have to “slipstream” the correct hard drive controller drivers into the XP setup process.

October 7, 2013 at 12:27 pm
(203) Tim Fisher says:

@Techsys: If it’s only happening after you overclock, I’d guess that some aspect of Windows (maybe a specific driver, maybe a Windows system file or set of files) has issues due to that. You could try making sure that your drivers are fully updated, BIOS is fully updated, and maybe try running <a href=”http://pcsupport.about.com/od/toolsofthetrade/ht/sfc-scannow.htm”>sfc /scannow</a>.
