I wanted to install Lubuntu (20.04) with btrfs root. I am using 20200208
media and during partition setup choose 'Manual' option and set
partitions as follows:

/dev/sda1 8M unformatted (selected flag 'bios-grub', from the installer GUI)
/dev/sda2 2G swap
/dev/sda3 18G btrfs for /

Continuing with installation with this option, the grub-install fails
complaining it could not see 'BIOS boot' partition. See attached
sceenshot.

Solution is to manually set 'BIOS boot'. May be one could do it
beforehand, which I did not try. What I did was to create partitions as
above and while installation was in progress, opened up a terminal and
manually set partition type to BIOS boot. I used parted and did 'set 1
bios_grub on'.

I checked on Kubuntu; if we choose 'Reservered BIOS boot area' option,
the installer (ubiquity) remembers this and grub-install finishes
successfully.
