Windows 10 VM boots to UEFI can't find vdisk after removing install ISO

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...
