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).

I'm not sure I understand what it is you did to install Win 7? Why did you have to use a USB stick? You go on to say that you have a CD and used your company license - wasn't the CD or DVD bootable?

It sounds like the Win 7 boot sector has been damaged. The way to repair it is by using a Windows 7 install DVD and booting your iMac with it. Hold down the "Option" key after you hear the chime and select the Windows 7 DVD as the boot device. When the Windows 7 disk comes up, select repair. See the following Microsoft Article.

Before doing anything make certain you have a backup of your Snow Leopard installation. Time Machine, SuperDuper, or Carbon Copy Cloner can be used to make the backup.

Regards.

Thanks for posting the Link. I had forgotten about the driver problem and the black screen. We'll see if the OP was able to repair his Win 7 installation using the MS repair method.

Regards.
