IMHO the old format should be avoided completely when possible.  Why
should we enforce it?

I think this problem involves having a previous ESP partition on the
disk (at least identified as such by parted), because auto-partition!
currently checks that before checking if the booted system has EFI
support.  When that's the case, it doesn't create the needed bios_grub
partition that might have been removed previously.

The attached patch solves that.  What do you think?

Happy hacking,
Miguel
