The Startup Repair tool in Windows Vista replaces important operating system files that might be missing or damaged. Startup Repair is an easy diagnostic and repair tool to use when Windows Vista doesn't start properly.
To begin the Windows Vista Startup Repair process, you will need to boot from the Windows Vista 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 Vista DVD. If you do not press a key, your PC will try to boot to the operating system that's currently installed on your hard drive. If this happens, just restart your computer and try to boot to the Windows Vista DVD again.
Note: Not using Windows Vista? Every modern Windows operating system has a similar operating system file repair process.
