I woke up this morning to see the grub rescue prompt complaining about some highlight color being invalid. Apparently the upgrade to 14.04 was installed last night after I went to sleep.
So I am booted up on my old 12.10 disk. I tried boot-rescue, but I get the message "please close all your package managers" when attempting the recommended repair (obviously, I dont have any open).
here is my boot-info from boot-rescue: http://paste.ubuntu.com/7283446/
My system has a windows8 disk (totally separate disk), as well as a linux disk using lvm .. both ssds. And also a large data disk.
