If it works, doublecheck the boot entry in the | bios. If it's efi and you have 2 efi partions on your system (each on a | different drive) try to get rid of the one you don't use - should be | sufficient to change the partition type. That's a problem: sda is on a sled that is permanently located; I could *conceivably* switch the cables but it would not be pretty. And I haven't been updating grub. As to the efi partition -- to the best of my knowledge i have only one, sda4, the purpose of which has never been even slightly clear to me, except that this can't possibly be the best way of doing things. There is none on the SSD, which is only 500 gigs. And again, this was working, in its current condition, until yesterday, when I shut down to add a couple of case fans. I had previously changed the partition labels to LABEL= in /etc/fstab; if that had any effect at all anywhere it is certainly well hidden.
