Dual boot question

I have XP and Vista on 2 separate hard drives. Seems I may have a sneaky
virus and I don't trust that the scans got everything so I want to reinstall
XP. Since it's best to have XP installed before installing Vista, can I
reformat and reinstall XP on the separate drive and will Vista even realize
it? Meaning, will Vista's bootloader be changed or will it just see the XP
boot info and not even know it was reinstalled?
Thanks

Depends on where your Vista boot files are. If they are on the XP drive,
you will have to run Vista start-up repair after the XP install.
