Thanks for that interesting tip. My GPT disks on C6 don't have it and
they boot normally.

It seems biosboot is indispensable when booting GPT partitioned disks on
older hardware that lacks EFI capability.


It seems the advantage of having a biosboot partition, at the start of
the disk, is the disk will successfully boot-up on EFI and on older
non-EFI BIOS-only systems.

One learns something new almost every day :-)

Thank you.
