Hi guys,

I have a Mac Pro 1,1 running OSX 10.6.8 that I need to put windows on. I have partitioned the disk and downloaded all drivers from apple. The thing is, I have a copy of windows 8 pro sitting around and would rather not pay 100 bucks for a copy of windows 7, and after doing a little research, found that you can indeed put windows 8 an unsupported computer. So, I inserted the disk, restarted holding alt, and selected the disk on the startup page. However, I get a dos page that says, 1. 2. Select CD-ROM Boot Type. The keyboard does not work, and I cannot do anything except shut the computer down.

So, I downloaded windows 7 as an iso image from Microsoft without the product keys and burned it to a disk. I repeated the process, but got the same message as before. Both of the versions are 64 bit, is this my issue? Or is it a matter of an unsupported computer? I'm thinking of buying windows 7 or 8 in 32 bit which I would prefer not to do, but if its the only way to get it working... Perhaps there's a way around the dos page?

My understanding is that your Mac Pro does not support the 64 bit versions of Windows in the same way you can only upgrade that machine to Lion. Mac Pro 1,1 firmware is 32 bit.

I bet that is part of the problem. IIRC that was the primary reason that machine does not support OS X beyond 10.7.5.
