Installing Windows 10 pro onto an older Mac Pro

So I have this 2006 Mac Pro 1,1 that I’ve had laying around and I wanted to put my old Nvidia 1030 into it, along with Windows 10 for a newer (stronger?) home machine.

So I burnt the downloadable ISO from Microsoft onto a DVD, tried to boot it up and got this:

Ignore the microwave…

I got stuck at this “Select CD-ROM Boot Type : ” prompt, which you can’t type anything into. Apparently it’s a common and known issue with 64bit boot code, as the older Intel Apple Mac’s are of course 32bit only. So there is a fix, you have to use something called “oscdimg” to rebuild the ISO with a 32bit friendly loader.

So first I just used 7zip to extract the downloaded ISO, and then create the new 32bit ISO with the following:

oscdimg -n -m -bc:\temp\Windows10\boot\etfsboot.com c:\temp\Windows10 c:\temp\LegacyBootWindows10dvd.iso

And yes, it boots!

Now what about those special ‘bootcamp’ drivers? Obviously under Windows 10 there is no nice way to get the ones you want. And what about which model/download package to get?

Then I found Brigadier!

It’ll probe your hardware type and grab the drivers for you!

  1. I installed Windows 10 on a MacMini1,1 with a broken CD drive via some stupid Boot Camp tricks: run Boot Camp to make the Windows partition, select the USB installer when it reboots… (which is uh, finicky) and the Boot Camp CSM doesn’t provide USB input emulation, and my Windows 10 install disk was dual arch, so it booted into the default option…. 64-bit. That wouldn’t work on a Core Solo. So then I edit the BCD to default to 32-bit instead, and Windows 10 just hums along. Then I slowly installed the Boot Camp drivers.

    Hilariously, it’s not as bad as you’d think it’d be! Once it loads, it’s tolerable as it’d get for a ~5200 RPM spinning disk.

    1. As much as I liked the idea of XNU, the NT kernel really does perform better on MAC branded hardware. Then again it’s nice to take such an ‘obsolete’ machine condemned to 10.7 as a maximum and run build 1809 without any further issues.

      1. The Mac Pro 1,1 will run El Capitan with some hacks, provided a compatible graphics card is present, as unofficially as it will run Windows 10.

        1. Yes, and I’d gotten it that far, and performance & lack of apps was becoming a thing. I was relying on Crossover (Wine) more and more.

          So I took the leap, and just installed Windows 10 instead.

      2. I almost wonder how hard it would be to do a “MINE”, starting perhaps from what already exists (e.g. gnustep) to run OSX apps on other OSes…

        1. After I’d built Darwin 0.3 I was able to run the NeXTSTEP UI, but the authentication wasn’t working.

          It may be possible if you know more about the frameworks
