iso image installer needs to be able to use bios-grub as well as uefi

[Leroy Tennison]

In the partitioning menu of the installer, if “Use as boot device” and “Add as another boot device” is selected (ultimate goal is RAID1) then a UEFI partition is created - no option to make it BIOS-GRUB (even for disks smaller than 2TB). On some hardware platforms the install will complete but, upon reboot, ends up at the grub-rescue prompt. I ended up installing Ubuntu 16.04 with RAID1 then using do-release-upgrade to get to Ubuntu 22.04.
