So I just got me new iMac (might I say it is awesome!). It's the 27' model with 2GB VRAM. I partitioned 50GB for Windows 7. Went through the install process and at the stage that I enter my username Windows gets ready to start then shuts down. When I restart in bootcamp, all I get is a black screen with a blink bar at the top left. Mac side works fine, but the windows side won't load. Even when I put the disk in it will bring up "press any key........" and it gets stuck on that as well. Any ideas?
