I have Lenovo X220 he also loaded only when partition support in the mbr. GPT table, and have a new EFI boot lead either to not recognize the media, or to reboot without warning. But in this scheme, the notebook is perfectly loaded with ZFS-only system => 63 234441585 ada1 MBR (112G) 63 234441585 1 freebsd [active] (112G) => 0 234441585 ada1s1 BSD (112G) 0 234441585 1 freebsd-zfs (112G)
