How do I resurrect Windows 2000?

Due to an attempt to use a Radeon 9500 Pro, which caused my system to randomly reboot many times, Windows 2000 apparently got corrupted such that it rebooted while booting (showed a blue screen for a second then rebooted). I don't think it's a virus, just a corrupted Windows 2000. I since copied the partition elsewhere on the disk and installed a fresh OS to use, but I'd rather go back to Windows that's already set up the way I want it.

So the question is, is there any way to resurrect that copy of Windows 2000? If so, how do I copy it back and convince the Windows boot manager to see it as the OS?
