Having drawn a coplete blank with trying to resolve my freezing mouse probs ( see here http://ubuntuforums.org/showthread.php?t=2185584) I though id see if I could solve the issues with an upgrade. I set update manager running but was offered only 12.10 and not 13.10. I assumed this was because I was running 12.04 and that I'd need to upgrade to 12.10 first, and then again to 13.10 - (is this right?).
Anyway having done the upggrade I tried to boot but it hung on the grub menu page. the ten second coutdown didnt move and i couldnt access any of the choices.
I ran Boot Repair (more than once in fact)
the results are here http://paste.ubuntu.com/6411939/
and here http://paste.ubuntu.com/6412009/
and here http://paste.ubuntu.com/6413100/
It instructed me to repair the boot sector with test disk, but testdisk kept returning a bizarre "No Hard Drive" error.
Gotta say Im completely baffled.
Anyone got any ideas?
