In Windows 7 and Windows Vista, Startup Repair has replaced the Repair Installation option that was available in Windows XP. Startup Repair replaces only damaged or missing Windows startup files. In a Windows XP Repair Install, all Windows files are replaced no matter if they work or not.
NOTE: System Restore and System File Checker in command prompt is available in Startup Repair.
Clear The CMOS
Clearing the CMOS will reset your BIOS settings to their factory defaults. It solves certain hardware compatibility issues.
To clear the CMOS, Enter the BIOS setup utility and choose to "Reset BIOS Settings" to their factory default levels.
Another way to clear the CMOS is to short the "CLEAR CMOS" jumper on your motherboard. These jumpers are usually located near the BIOS chip itself or near the CMOS battery.
