Verkar vara ngt bråk med grafikdrivrutiner
"Well I have/had Windows 7 32 Bit and 64 Bit both running in Bootcamp in my iMac 27" i7 8 GB (ignore me for other non ATI iMacs)...
To get it to work you need to delete a file from the rescue console right after you have the blank screen...
The file is located in the Windows Drivers folder and named: ATIKMDAG.SYS
After deletion of that file the system boots up and you can use the mac cd to install the remaining drivers and stuff.
