Hey Wizard, Thanks for the link, and apologies for the delayed reply. Life gets busy sometimes, eh? Anyway, I attempted to install grub onto the RAID, as that last link seems to suggest, but no dice, unfortunately. I've attached my commands run and their output, for reference, and the output of the boot-repair tool's "Boot info" option. Hopefully something there gives you a clue. I'm close to whacking a standalone drive in to install a new OS onto, and boot off, and then just mounting the RAID off my existing drives in that new OS. Thanks for all your help so far, mate.
