Recently I upgrade my system from XP to 7, but then today I messed something up so I figured I would just reinstall it because I figured it would be easier. I was able to load XP back on alright, but when I went to use the upgrade discs to 7 is when I ran into problems. When I put the disc in it says loading files, and there is a progress bar at the bottom, and when that's done I get the "starting windows" text but Windows never starts. Any suggestions on what I should do?
