I'm trying to load Windows 8 (And have previously tried everything with Windows 7) on my Mac Pro early 2008 with Mountain Lion, and cannot get the installers to initiate.


When I start the bootcamp assistant and reboot, my mac freezes before ever getting to the installer. When I reboot and hold option to manually select the installer, it freezes as soon as I select it. I've tried this from a DVD, USB, and even an install partition i setup on my HD, all with the same freezing results. This is a legitimate copy of Windows 8 system builder I'm working with and have installed it perfectly in Parallels.


I should note I upgraded my video card a long time ago to a gt 120, so I'm wondering if the video card might be the problem. I've installed Windows 7 with this video card in the past so I'm guessing this is a Mountain Lion/Bootcamp 5 issue.


Has anyone else with a Mac Pro 2008 succesfully installed Windows 7/8 from Mountain Lion/Bootcamp 5?


Any input would be immensely appreciated!

Mac Pro, OS X Mountain Lion (10.8)

    There are no Windows 8 Bootcamp drivers. Windows 8 is not supported.


    Use Parallels or Fusion to install Windows 8. By doing so you eliminate the need for drivers since the virtual machine creates virtual hardware and drivers.


    Once the Windows 8 Bootcamp drivers are developed and released you can then install using Bootcamp Assistant.


    Read this forum. Some people are posting that they had some success with the Bootcamp install. but if you have to rely on your computer then don't take the chance.
