Power Mac G5 A1117 emc 2023

Apple's method of running Windows is BootCamp, that only works with Intel-powered Macs. Yours has a Motorola processor.

Even older Intel Macs cannot run Win10 so I suspect you are out out of luck. You make be able to run an older version of Win if you can find old versions of virtual machine software.

The only way to install a Windows OS in a G5 would be using Virtual PC or Qemu. Both options are software based emulations, and should be run under Mac OS X Leopard.

Also, Allan: The G5 processors was made by IBM (internal IBM name 970), not Motorola. The last Motorola-made processor on Apple machines was the G4 (internal Motorola name 7400). I would kindly suggest that you refer to this era of Macintosh computers "PowerPC macs", as calling them "Motorola" would greatly confuse new users, as any Google search would redirect them to m68k processros or even early 2000s phones.

Apple-IBM-Motorola was the backbone of PPC & Power Mac tech.

There is an intertwined history; as names changed, tech evolved.

Overly critical of part of this story does little to improve it overall.

Good luck & happy computing!🌻🌤
