I have two almost identical PC's:
Asus Q270M-C Motherboard's
i5-7400 CPU's
64G ram on both
Docking solution för SSD in the front so I easily can move the SSD between the two PC's
I installed Qubes 4.0.3 and it works fine. When I move the SSD to the other PC, it will not boot. It goes into the BIOS. Only when the SSD is in the origin PC, where I installed Qubes it boote in a correct way.
Does it have something to do with Legacy/UEFI selection?
