You can run the Startup Repair tool manually if you have a recovery option preinstalled on your computer, or have the original installation disk, or have the system recovery and repair disk.

If you have Startup Repair preinstalled on the system:

  1. Remove any CDs, DVDs or USBs from the system
  2. Restart your computer
  3. Press and hold F8 as your computer boots, but before the Windows 7 logo appears
