If all else fails try an in-place upgrade:
If you can’t repair a Windows system that won’t boot and you don’t have a recent backup, you can perform an in-place upgrade. Doing so reinstalls the operating system into the same folder, just as if you were upgrading from one version of Windows to another. An in-place upgrade will usually solve most, if not all, Windows boot problems.
Performing a Windows in-place upgrade is pretty straightforward. To begin, insert the Windows CD into the drive, restart your system, and boot from the CD. Once the initial preparation is complete, you’ll see the Windows Setup screen. Press [Enter] to launch the Windows Setup procedure. In a moment, you’ll see the License Agreement page and will need to press [F8] to acknowledge that you agree. Setup will then search the hard disk looking for a previous installation of Windows. When it finds the previous installation, you’ll see a second Windows XP Setup screen on the next page.
This screen will prompt you to press R to repair the selected installation or to press [Esc] to install a fresh copy of Windows. In this case, selecting a repair operation is the same as performing an in-place upgrade, so you’ll need to press R. When you do so, Setup will examine the disk drives in the system. It will then begin performing the in-place upgrade.
This retains ALL of your files and folders, whereas a format removes them.
