If Startup Repair finds a problem with an important operating system file, the tool may suggest a solution of some kind that you have to confirm or may solve the problem automatically.
Whatever happens, follow the prompts as necessary and accept any changes suggested by Startup Repair.
If you want the Startup Repair to work properly, you must remove any flash drives or other USB storage devices, like external hard drives, from your computer before running the tool. Due to the way some computers report the storage space on USB connected drives, the Windows 7 Startup Repair may incorrectly report that it found no problems when in fact there may actually be an issue.
If you've already started, or completed, the Startup Repair and you realize that you have a USB storage device connected, just remove it and restart these instructions at Step 1.
