Hoping someone can help - I have an iMAC and wiped the whole thing out so that only Windows XP is loaded on it. It's worked great this way. Attempted to perform Vista upgrade and now get BSOD when booting. Trying Windows Repair but it seems to be endless doing the startup repair. Have no other devices attached except keyboard and mouse. Wondering if there is something else I can do to get it to boot to Vista, or should I just restore back to XP - thanks in advance.
