So i gave a friend of mine a hand with his 2009 27" i7 iMac by installing Windows 7 for him. Unfortunatly for some reason after you get through all the meat of the install and it restarts to finish off and ask for personal information but here's the problem. The display is showing nothing! You can hear the fans are on and booting into mac is fine but I can't get any farther with the Windows 7 installation because i can't see anything! I know the disc works because I installed from it the night before. Any help will be greatly appreciated. Thanks.
