Whenever Win 10 VM is started, it first drops to UEFI shell, requiring manual intervention. Immediately after the VM boot-up, black screen with text "Press any(?) key to...??" (currently it's hooked to low-res TV, and the margins are cut off, so can't read the text completely). No matter what you do there, you still end here:   UEFI Interactive Shell v2.1 EDK II UEFI v2.50 (EDK II, 0x00010000) Mapping table     FS0: Alias(s): CD7a1....         PciRoot(0x0)/Pci...../Ata(0x0)/CDROM(0x1)
