I just installed window 7 on boot camp partitian. The only trouble was getting rid of the old ati drivers. Actually deleting the line was easy once i was able to get the imac to restart into windows 7 setup . Now the trouble i have after installing the boot camp drivers off the snow leapard disc is the sound keeps muting then the keyboard and mouse freeze up. When i go to the device manager it appears microsoft is installing its own drivers for the mouse and keyboard. Its getting very frustrating other wise everything else would be fine
