I bought a new SSD drive with the idea of running my Ubuntu system on it and leaving the other two SATA drives (which are configured in a RAID array) for storage only.
Ubuntu installed with no problem, but it turns out that my motherboard doesn't support AHCI and it doesn't see the SSD drive at all -- so I can't configure it to boot from the SSD.
Can I, theoretically, install GRUB on the SATA array and configure it so it boots the SSD?
When I run grub-mkconfig, it identifies the system installed in the SSD but it spits out the following error:
### BEGIN /etc/grub.d/30_os-prober ###
