I prefer to downsize these days and want to keep it all in one Mac if I can, either as a dual-boot setup (for accessing Mac hardware such as my GPU for reflashing it), or in a virtual machine such as Virtualbox or VMWare Fusion Player (both free), or both solutions each for their own use.

There's some USB hardware like an EPROM programmer and other things which is Windows-only, then there might be similar, often older (Windows 95 etc.) software for use with some hardware or specialized taks further down the road that I need to use. I'm going to try out all the Windows software I know I need to use.

multiple SSDs and hard drives in various internal drive bays My mid-2010 Mac Pro 5,1 has been upgraded: and is it even possible to buy a (legit/legal) license for something other than the current version(s)? How about system requirements? I assume older Windows versions run more efficiently on an old Mac like mine, but perhaps more buggy as well. 32-bit or incompatible for other reasons as well)?Īnd I understand that I should stay away from OEM versions of Windows because if you change your hardware setup (add more memory, remove/add drives etc.) that license will no longer be valid, right? The big question is which Windows version should I get? Is the latest version (Windows 11) backwards compatible, or is it like with MacOS where it's no longer possible to run older Mac-apps (i.e. when installing new apps, or other error messages which I don't understand) I finally gave up, downloaded the Windows 10 ISO file from Microsoft, installed it on a separate drive and it's worked fine! Having struggled to install Windows 7 on a separate drive several times without much success (it works but I keep getting problems with missing security certificates etc. Every now and then I also need to use software which isn't available for MacOS (and won't work in a virtual environment).

I have a mid-2010 Mac Pro 5,1 where I've recently had to install Windows on in order to reflash a PC type graphic card (GPU).
