Hi, I need help with a windows 7 installation I tried recently on my imac (snow leopard 2010/11). I did the install with help over the phone from apple and managed the install Windows 7. When I tried starting up windows it loaded correctly, we got the console/bios thing an then the familiar windows logo. and then, It suddenly all goes black. I waited because the apple person told me t wait. I waited over half an hour and nothing happened. By that point I decided to turn the computer off and on again. When the computer restarted, I got a windows error message telling me that windows had failed to shut down correctly and that It may have done this to correct data, and a series of restart options come up, all of which lead to the same conclusion. If anyone can help that would be much appreciated!
