I have Mac Pro 1,1 (2006 version) running Lion 10.7.5. Bootcamp on this model officially supports up to Windows 7 x86 though people have reported being able to run Windows 10 x64. I downloaded a Windows 7 Pro x86 ISO and checked its integrity by creating a virtual machine and getting it to load the installer. Then, I burned the ISO to DVD on a Windows 10 PC. The DVD is detected on my MacBook (7,1 running a Mojave patch) but not on the Mac Pro. The Mac Pro DVD drive works since it can play movies and load other software install DVDs. Could someone explain why this isn't working and how to get this model to load a Windows installer?
I tried a bootable USB but the default boot loader wouldn't detect it. I tried refit as an alternative boot loader but it still didn't work. I tried creating a bootable USB from within the Mac Pro OS by editing the flags of supported USB boot models to get the "create USB install disk" option to appear in the boot camp installer. It still doesn't work.
I tried enabling access to an external Apple "superdrive" and performing the normal terminal patch to get it to work. The external superdrive spits out discs.

I figured out a workaround that is probably more unconventional and useless to most people.

Hope this helps someone though I doubt it because most people don't have access to the equipment that I used. There are other methods involving what appears to be cloning virtual machine images to HDDs but I haven't attempted. This solution seemed easier to me.
The problem still puzzles me. The Mac Pro DVD drive works fine as it is able to play movies and install software. However, it just gives a finder popup for a "blank DVD" with the Windows install DVD inserted. On the other hand, my MacBook 7,1 recognizes the DVD perfectly. I didn't have a spare IDE DVD drive to try in the Mac Pro but I think the drive is fine. Generally, I've found the Mac Pro to be subject to more issues than other Apple products because of its ability to be customized. I suspect this is just another example. This Mac Pro should have been easily able to perform this bootcamp installation as it is officially supported to run bootcamp with Windows 7 x86.
