This underlines that fact that it's always wise to have a backup operating system installed - that way you can quickly determine whether a fault is hardware or software related.

I dual-boot Win2000, XP and Vista but there is no reason why you can't install multiple 2000/XP images on a single hard disk (not sure about Vista but it's probably possible).
