Startup Repair
Startup Repair is a Windows recovery tool that can fix certain problems, such as missing or damaged system files that might prevent Windows from starting. Startup Repair is located on the System Recovery Options menu, which is on the Windows Vista installation disc. If your computer has preinstalled recovery options, it might also be stored on your computer’s hard disk.

Reinstall
If no other options have solved the problem, and you are sure that your computer’s hardware is functioning normally, you might need to reinstall Windows. A custom (clean) installation of Windows will permanently delete all of the files on your computer and reinstall Windows, so only use this option if all other recovery options have been unsuccessful. After the installation, you will need to reinstall your programs and restore your files from backup copies.

- Try cleaning your Windows installation disc. It might be scratched, smudged, or dirty. Clean the disc with a soft cloth, insert it in the CD or DVD drive, and then begin the Windows installation again. If your installation disc is damaged, you might need to replace it.

- Make sure your CD or DVD drive is working properly. If it isn’t, the disc might be vibrating too much for the laser to accurately read the data. For more information about this problem, consult your hardware documentation, or contact the CD or DVD drive manufacturer.

- If your computer has multiple CD or DVD drives, make sure your computer is trying to locate files on the correct drive. If your computer has a feature to disable CD or DVD drives that are not being used, disable the drives that you aren’t using. Otherwise, try inserting the disc into a different drive, and then start the installation again.

- Check to see whether a virus is on your computer. Run an antivirus program to scan your system and identify needed repairs. Be sure to disable the antivirus program before beginning the installation again.
