Is there a vm out there. i can use to test if my AIO works properly. And if my install usb stick, can boot both in Legacy, and in uefi. i would like to test my own AIO, in a vm, before, i install them on a real maschine.
I would suggest installing virtualbox, map your install usb stick (or a iso of the contents) in a new virtual machine and try to boot from that.
