I would like to install Ubuntu 20.04 Focal Fossa on a machine with two hard disks using RAID 1.
Unfortunately it seems this doesn't work. If I use the "Create Software RAID (md)" option and select both my disks the installer tells me:
If you put all disks into RAIDS or LVM VGs, there will be nowhere to put the boot partition.
What options do I have to accomplish this?
