To begin the Windows 7 install process, you'll need to boot from the Windows 7 DVD.
- Watch for a Press any key to boot from CD or DVD... message similar to the one shown in the screenshot above.
- Press a key to force the computer to boot from the Windows 7 DVD. If you do not press a key, your PC will attempt to boot to the next device in the boot order, which is probably your hard drive. Since your hard drive has no operating system on it, the boot process will fail.
Note: If you see a "No Operating System Found" or "NTLDR is Missing" error here instead of the screen above, the most probable reason is that your PC is not setup to boot to the CD/DVD drive first. To correct this problem, you'll need to change the boot order in BIOS to list the CD/DVD drive first.
Note: It's perfectly fine if, instead of the screen above, the Windows 7 setup process begins automatically (see the next step). If this happens, consider this step complete and move on.
