Ok I'm attempting to get Windows 7 to install on my 27" iMac. I did the fix for the drivers, successfully booted into windows 7 once, went to restart into Windows. When I boot into Windows 7, I get a black screen, then the iMac just continually reboots, and reboots, and reboots, until I hold alt to boot into OS X or until I turn the iMac off. I googled and found no answers. Anyone know what might be happening?
