I just bought a brand new mobo, EVGA nForce 680i SE Sli and also an Intel Core 2 Duo E 6750 cpu. I am planning on switching out this mobo and cpu out with the new hardware. Currently, I have vista and xp dual booted, and I plan on formatting the drive with vista on it but want to keep the xp partition. If I plan on dual booting after putting the new mobo and cpu in, is it possible to just install xp and still have all my settings, registry info, etc and anything needed to do so or would it be necessary to format and install xp clean? I've already decided i wanted to dual boot again, although I realize the lack of needing xp and just stick to vista.
