Method 4: Use Startup Repair on a computer that has a preinstalled recovery option on your computer

Important: This method is available only if Startup Repair is a preinstalled recovery option on your computer.

 

If you do not have a Windows 7 or Windows Vista disc, and Startup Repair is a preinstalled recovery option on your computer, follow these steps to repair startup files:

1. Remove all floppy disks, CDs, and DVDs from your computer, and then restart your computer by using the computer's power button.
   • If your computer has a single operating system installed, press and hold the F8 key as your computer restarts. You have to press F8 before the Windows logo appears. If the Windows logo appears, you have to try again by waiting until the Windows logon prompt appears, and then shutting down and restarting your computer.
   • If your computer has more than one operating system, use the arrow keys to highlight the operating system that you want to repair, and then press and hold F8.
2. On the Advanced Boot Options screen, use the arrow keys to highlight Repair your computer, and then pressEnter. (If Repair your computer isn't listed as an option, then your computer doesn't include preinstalled recovery options, or your network administrator has turned them off.)
3. Select a keyboard layout, and then click Next.
4. Select a user name, type the password, and then click OK.
5. On the System Recovery Options menu, click Startup Repair. Startup Repair might prompt you to make choices as it tries to fix the problem and, if it is necessary, it might restart your computer as it makes repairs.
