My computer came with XP when i bought it(4 years ago). Two years later i upgraded it to Vista without a problem. Now i have decided to reformat my computer with Vista. I changed the boot sequence so the DVD drive is first. I put my disk in and the load bar at the bottom of the screen appears, as if it was going to reformat but then the screen goes black. I waited about 30 minutes just to see if the computer was taking along time to load but it stayed black. I dont think my vista CD is broken since I have used it before. I even tryed another Vista CD that my dad has but the same thing happened. I was curious if I am doing something wrong or if anybody else is having the same problem?
