The low-probe option requires a device
(Somehow I don't think this is what you were expecting - I assume the 
command is incomplete.)

(No output at all.)

cat: /boot/grub/grub.cfg: No such file or directory

Hope this all tells you more than it tells me - although the UUID for 
/home appears to match.

This problem is not unique to me - there seems to be a whole thread on 
it in Ubuntu Forums which I haven't yet had a chance to read in detail.  
However it does make it appear less likely that it's down to a failing 
hard disc.
