Run Windows off an internal hard drive, no boot camp

[JMorgue]

Have a 2009 Mac Pro that thinks is a 2010.

It has a pair of quad-core processors and 16 gigs of RAM, for now.

I have High Sierra installed on the first hard drive, and Windows 10 on the second. The 3rd drive is waiting for a partition. I will update the OS after updating the video card.

The Mac Pro will not run Windows 10, according to Apple, so it is impossible to boot camp. Beleave me, I spent days trying to figure out how to force it.

Have a 2012 Mac Mini running boot camp and Windows 10. I am going to move the license of Windows over to the Pro as soon as I can get Fusion to work.

The fusion that I have a license for is version 10, I downloaded a trial of 11 and I cannot create a virtual machine that runs off the physical hard drive. My research on fixing this has not been helpful. I am seriously considering simply copying the entire Fusion folder from my mini and copying it onto the pro, and seeing if the existing Windows 10 configuration will simply boot, because both machines have Mac OS on drive 0 and Windows 10 on drive 1.

And all advice will be appreciated..

I am not above installing Windows 7 on drive 1, when swapping it out for the existing Windows 10 Drive to get bootcamp to work, but that will be a hassle as I can only install off of a thumb drive and I understand that creating those bootable thumb drives are a pain in the butt. I have gone through and modified the boot camp set up software trying to get it to let me install off the optical drive, but for some reason it just doesn't want to...

AFAIK Fusion 11 isn't supported on the 2009 Mac Pro, and fusion only supports virtualizing boot camp VM's based on what Apple supports in boot camp on that machine.  Both are limited by the actual capabilities of the CPU and other hardware, not what the BIOS thinks it is.

One thing that definitely won't work is copying fusion configurations for boot camp VM's from one machine to another.  You can copy standalone VM's (not on a physical drive), but even then, you'd need to have the VM configured in a lowest compatibility mode.  That's probably your best option in this case - create a regular Windows 10 VM in Fusion 10 from scratch.

I hate to say it, but that's really old hardware - it's probably time to look at upgrading to a new machine.
