I have a 2006 Mac Pro 1.1 with Radeon x1900. I finally figured out how to make a bootable DVD of the Windows 7 64bit installation dvd and ran bootcamp. I'm running OS X 10.6.8 and it says there are not bootcamp files available. I ran the program thinking I'd use my installation disks anyway. Well, Windows appears to load fine but when I get to the final setup and reboots of Windows I get several pixelated "pink ribbons" running vertically on the screen. It just gets worse from there but the installer continues to run and I can pretty much make out what its saying. Eventually I get a BSOD and the Mac reboots itself. I've tried safe mode, tried command prompt but eventually it always comes back to a screen that says there was a problem and I need to reinstall Windows. But I can never get past that screen that's garbled pretty much anyway. I'm curious if there is a way around this or if there is a conflict with the x1900 video card. If anyone knows I'd appreciate any feedback. Thanks.
