For what little it's worth, Lenovo BIOSes that support UEFI and GPT have made the assumption that any GPT partitioned disk is UEFI and fail to see a bootable drive if it is an MBR GPT disk. I have found this fairly easy to work around on my system by having a disk that has traditional partitions with booteasy. I make his my "boot disk" (ada0 with BIOS set to boot from that drive) and then tell booteasy to boot from "Other DIsk". N.B., there is no ZFS involvement here, just working around the boot issue. I should also mention that I received a note that Lenovo may have fixed this in the latest BIOS, but I have not gotten around to testing. -- R.
