The installer does not like that, and wants to create a larger bios_boot partition. But I persisted with that, and it worked just fine. It works fine that way with "btrfs" file system. So if the objection to a bios_boot partition is the disk space wasted, you can put that partition in sectors 34-2047 so that no useful disk space is actually wasted.
That's interesting and worth knowing. Thanks!
I guess it only needs the first 512 bytes for a boot sector, so a 2MB partition is plenty.
What "it" do you mean here? bios_boot partition contains grub2 core.img which (for btrfs on BIOS) is about 40K. Still fits into 2M space but no more into legacy 63 post-MBR sectors.
