barbet Posted July 7, 2010 Share Posted July 7, 2010 hey, after a lot of trouble I got windows 7 ultimate working on my iMac 27" 3.06 ghz jan. 2010 (bootcamp 3.1) with ATI videocard. I used the usb stick trick (with master boot) during installation, and I got it working. So I moved on, installed some small programs. 2 days later I wanted to use my windows 'side' again, however when I start it, i only get a black screen. And even after a reset i don't even get a question to startup in safemode or something. Just a black screen. Not an intro picture (as I got at the black screens during the installation). i tried removing atikmdag.sys but didn't work (thought it was a driver issue again, and hoped to solve it this way). I really thought i had it working. i installed all the updates, all drivers, everything worked, but now I only get a stupid black screen. It is really frustrating. Hope anyone could help me. Greetz, Barbet PS the installation was via a burned cd from a friend, i installed it for my work with a company license. However the cd can be a downloaded version (which I am 100% sure is a good version). Link to comment Share on other sites More sharing options...
MBP13 Posted July 14, 2010 Share Posted July 14, 2010 Hi, I've been trying this for weeks and can't get it working either. Was yours a fresh install or an upgrade from a different Windows? I'm trying to do a fresh install so if you could let me know what the USB method you used was then i might get into your situation and be able to help find a work around. The problem i have is, when i try to get the drivers for the graphics/ bluetooth issue i can't as it's an EXE and i am doing a fresh install not an upgrade so i can't do the windows side. Thanks, Martyn Link to comment Share on other sites More sharing options...
