Recently I was making a Boot Camp installation of Windows 7 on my iMac, however, it did not go as smoothly as expected. During the installation process the screen went infinitely black, and it was not possible to continue the installation process.
- Boot Camp 3.0 (Mac OS X Snow Leopard)
- Windows 7
Doing a little search, I found the following solution on how to fix the problem.
Update: Apple has made a support article on the issue: http://support.apple.com/kb/TS3173
Solution (step by step from the beginning):
- Run Boot Camp Assistant from Mac OS X Snow Leopard (Applications -> Utilities)
- Create a partition for the Windows installation using Boot Camp Assistant
- Plugin your install disc and install Windows 7
- The system will reboot a couple of times during the installation
- The problem: The second time the system reboots, you the see the Windows red-green-blue-yellow animated logo, and then the screen goes black and hangs infinitely.
- Press and hold the power button on your iMac until it shuts down.
- Start the iMac again holding “alt” key, so you can select and load Max OS X Snow Leopard again.
- Run any application that let you work with NTFS partitions (e.g. Paragon NTFS for Mac OS X or MacFuse)
- Find the file “C:\WINDOWS\SYSTEM32\DRIVERS\ATIKMDAG.SYS” on your BOOTCAMP partition, and simply delete it.
- Restart you iMac, and boot up Windows 7
- Now Windows 7 should boot normally
- Run update windows utility and install Boot Camp drivers from the Mac OS X install disc
