I don't really need EFI support for the VM, I can live without it.

I'm using the virtualbox package provided in the official Arch Linux repositories. Also using nvidia proprietary drivers from the official repositories. I don't think either of these should be a problem.

I'll try putting the ISO on an IDE controller. Do you know if Microsoft has the md5 checksums for Windows 10 ISOs listed somewhere to compare to? I downloaded the ISO from
here.
