Point taken. Trixe d-i doesn't boot in UEFI on this host, which would suggest that the filesystem type used for the root partition may well be a red herring. What googling the error shows is lots of people on Ubuntu derivatives with hosts booting via UEFI to a btrfs root partition. Some of the reporters claim that making a fresh install using ext4 for the root partition solved it. This suggests that the error about unsupported option (subvolume) may be the cause. Others report that it reinstalling with an ext4 root partition did not solve it. This suggests a larger issue with recent GRUB code changes. Martin-Éric
