I had a dual boot on my computer which was XP and Windows 8 Beta. I put the Windows 8 upgrade on XP. Now I have two Windows 8 that I can boot into. My computer say that my C drive is my system, and Default drive. However my Windows 8 upgrade in my D drive because it has Windows old on it. Now because of this mess I have to do restore points on both drives because I'm thinking that there are some system files on the other partition, the C drive. What I would like to do in delete my C drive making by Windows 8 upgrade the C drive instead of the D drive. What would you do?
