Error when trying to update: grub-probe error cannot find a grub drive for /dev/sdd2

http://unix.stackexchange.com – When running a fresh install of Ubuntu 12.10 I try to install updates, but half way through it reaches this error when updating grub, says "done" and the updates just hang. Exiting at this point makes it impossible to run any other update commands (because dpkg is locked), and as an added bonus trying to launch firefox causes the whole system to crash. I have no idea what grub is trying to do here or what the error even means. It tells me to check device.map (there is no device map). I ran grub-mkdevicemap and now I do have a device.map file, but I don't see what I could possibly need to chan (HowTos)
