I am getting ready to build a brand new computer from scratch with 2 WD Velociraptor HDD's. I want to set them up in a RAID 0 for the speed. I also want to dual boot with Windows 7 64-bit and Windows XP 32-bit. My question is... what is the proper way to dual boot these 2 operating systems, and will it work with 2 HDD's in RAID 0? As I said, this is a new build that I haven't started yet. I already know how to set up a RAID array. Just don't know how to dual boot.
