Everytime I run Windows under Parallels, it starts up fine, with the pop up that says "Activations successful." But once I run Windows under Bootcamp, it said that my Window is counterfeit, and then it log me off. I can't even get to the desktop under bootcamp. The copy of the Windows that I am running is the one that I brought from school, so I'm sure it's not counterfeit. Does anyone have any idea what is going on? I really need it running since I have to do homework on Microsoft Access. EDIT: It also said that I need to insert the Vista DVD to reactivate Windows. If I do insert the DVD will everything that I have be deleted?
