So I have had Windows XP Pro 64bit on a seperate hard drive for a while that I have installed first. I just decided today to partition my second hard drive and put Vista on it. The installation went fine.. but sometimes i get corrupted errors and the Main partition for Vista is listed as C when its listed as E in XP. This is causing problems. How can I make it so it stays E? This has been baffling me. Any help would be appreciated. thanks!
