Can anyone give me some advice on my computer problem. I have windows vista on a dell laptop. Its been playing up for a while, and I have been having to switch it off by the power key, but now when powering up it will not go past the black screen that says microsoft corporation at the bottom. I have tried the repair and also tried booting up from the vista DVD, but I select install vista and the option to upgrade and keep my files is greyed out. It says to do this from Windows, but as I cant get into windows I cannot do it! Can anyone give me any idea.
Thanks for ideas in advance
