The SYSPREP method usually allows you to avoid reinstalling Windows (see here
) but you have to run SYSPREP before changing motherboards. If you've switched to a motherboard with a different chipset then Windows almost always has to be reinstalled unless you try the SYSPREP method. You may still be able to make it work by going back to your old motherboard. Personally I'd take the opportunity to do a fresh install anyway. It's a good idea to start with a nice new installation of Windows from time to time anyway.
There's also a repair method (see here
) but it apparently isn't very reliable.
- Reportedly, Windows 2000 and XP can be tricked into doing this stuff for you. The procedure is this: Shut down, install your new hardware, power on, and enter your system BIOS. Make sure your First Boot Device is set to CDROM. Insert the Windows 2000/XP setup CD and boot from this disk. (You may have to "press a key to boot from CD" as the prompt says.) Skip the initial prompt asking to repair your existing installation. Then proceed to the screen where you select a partition, and choose your existing Windows partition. Setup will detect your existing installation and ask you to repair. Say yes. When Windows Setup is complete, you should have a fully working installation with all your old user and application profiles. Everything should be intact, except your hardware and driver settings, leaving it fresh for your new motherboard.
