I couldn't find this issue and was wondering whats going on.
I install windows 10, it works fine.
Sometimes rebooting I will have to select the boot device in UEFI, sometimes when I remove the virtio iso or install iso (since I don't need them anymore cuz the vm is installed) I get dumped into UEFI bios...
