SOLVED Bootable USB won't work with 11.2. Works with 9.10

Bootable USB won't work with 11.2. Boots with 9.10 without a hitch.

Hardware:
GA-Z68X-UD3H-B3 (Bios version F8)
12GB RAM
64GB USB thumb drive

All other drives are disconnected.

When I try to boot from my USB drive I get a weird error. When I try to google it that I don't find anything useful. Se picture. I've successfully booted to Ubuntu from the same USB thumb drive. I've tried writing the image with Win32DiskImager , Rufus and Etcher.

I've set my BIOS to EFI, and USB CDROM as boot device. I've tried USB HDD too. Not really sure what to try now. I could provide pictures of BIOS settings.

Works after a BIOS update and booted in UEFI.
