I have a system with a HDD and a SSD. I was not wholly attentive when installing. I've done it many times on other systems and never had a problem so I was a bit trigger happy...
But with this system, somehow the HDD ended up being the boot drive while the SSD is the system drive. I don't understand at all, but that's what it looks like.
So I want to, I'm guessing here:
-- make the SSD bootable -- install GRUB to the SSD
