I believe this is due to a lack of, or duplication, of UUIDs (not to be confused with PARTUUIDs) on some partitions, as manually assigning them allows my computer to properly detect the attached devices and boot from the GuixSD one (although not successfully). > udisksctl loop-setup -rf guix-system-install-1.0.1.x86_64-linux.iso Mapped file guix-system-install-1.0.1.x86_64-linux.iso as /dev/loop0. > sudo blkid -o list | grep ^/dev/loop0 | cut -d" " -f1 | sort /dev/loop0 /dev/loop0p1 /dev/loop0p2 /dev/loop0p3 /dev/loop0p4 > sudo blkid -s UUID | grep ^/dev/loop0 /dev/loop0: UUID="1970-01-01-19-49-46-83" /dev/loop0p2: UUID="C920-B8AE"
