vista came installed on my computer and i put windows 7 on there about a month ago! Well i want to take vista off my other hard drive but it wont let me. Will i have to remove windows 7 1st then remove vista? I have a lot of things on windows 7 and nothing on vista plus my friend is about to show me how to run lunix and i don't want 3 OS on my comp! All i'm trying to do is remove vista with out taking off winodws 7 and losing all my videos and music!?!?
