So I ran an apt-get dist-upgrade today and it broke booting
gurb-pc wasn't updated (it was last updated on my system on the 2nd of
march) linux-image-3.2.0-2-amd64 however was updated & it ran
update-grub as it should.
https://help.ubuntu.com/community/Grub2#Command_Line_and_Rescue_Mode
When I turn my PC on I end up at the grub> prompt & if I folow the
instructions on the page above & type
set root=(hd0,1)
linux /vmlinuz root=/dev/sda1 ro
initrd /initrd.img
boot
the system boots. once booted I run one of the commands below & reboot
update-grub2
grub-install --root-directory=/ /dev/sda
dpkg-reconfigure grub-pc
only to end up at the grub> prompt again.
I have nice sata removable hard drive bays so when I'm doing this the
USB drive is the only drive connected to the system

Any help would be greatly appreciated.
Thank you for your time.
