Use Recovery Console:

When a Windows XP boot problem is severe, you'll need to usea more drastic approach. The Windows XP CD is bootable and will provide youwith access to a tool called Recovery Console.

To boot from the Windows XP CD, insert it into the CD-ROMdrive on the problem system and press [Ctrl][Alt][Delete] to reboot thecomputer. Once the system begins booting from the CD, simply follow the promptsthat will allow the loading of the basic files needed to run Setup. When yousee the Welcome To Setup screen, press R to start the Recovery Console.

You'll then see a Recovery Console menu. It displays the foldercontaining the operating system's files and prompts you to choose the operatingsystem you want to log on to. Just press the menu number on the keyboard, andyou'll be prompted to enter the Administrator's password. You'll then findyourself at the main Recovery Console prompt.

Use system utility software like RegInOut after restarting windows.
