If you are up for experimenting, see if either of these results in your
system booting:
gpart set -a active ada0
gpart set -a lenovofix ada0

Although both of these should only impact BIOS boot, not UEFI, you never
know.

The other option is to try an ESP (EFI System Partition) that is
formatted FAT32 instead of FAT12/FAT16)
