I downloaded and checked the Qubes OS 4.1.0 image and wrote it onto an USB stick.
When inserting the stick to boot (on a different computer), I'm offered UEFI boot and normal boot by BIOS.
"Nice, UEFI" I thought, but somehow that does not work (see attachment). Well, I think UEFI boot should work for Qubes OS, too as Tails has a working UEFI for quite some time now, and legacy boot is increasingly rarely supported on new hardware (IMHO).
OK, trying the other (compatibility) mode, boot also failed (see other attachment).
Now I wonder: Is my stick defective, did I have a write error, or is the image defective?
