If I understand correctly, it is a problem of some BIOS laptops. 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

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)
