So I just installed a legit copy of Windows 7 Ultimate on my new 13" MacBook Pro via Boot Camp. It worked fine at first, as in on the first boot up it was fully functional but still needed the Windows on a Mac drivers from the OS X CD installed. So I installed them and restarted, only to find that when I try to login, the computer freezes on the "Welcome" loading screen. I've tried completely reinstalling twice now, and tried booting in safe mode, but nothing so far has worked. I googled the problem and found nothing helpful, and couldn't find anything on a search in MacRumors. This is really frustrating me as I need to use Windows for several applications that aren't available on Macs. Anyone have any suggestions to get this running? I'd really appreciate any help I could get, thanks.
