I installed Win 7 on an old 100 GB SATA HDD I had laying around. Now I have my old XP SATA HDD and the new Win 7 SATA HDD and I'd like to be able to choose which OS I boot to. Currently I have to switch SATA cables to the MB to change which drive boots (which is painful). I don't know anything about the new Win 7 boot manager and I really don't want to change anything on my XP drive. I just want to add XP to the Win 7 boot manager. Any ideas?
