Root failure after Ubuntu 10.04 to 12.04 upgrade
I have been running Ubuntu 10.04 LTS since its release, on a Dell Inspiron laptop. The hard drive is partitioned, with Windows Vista still installed (though not used for years and only kept as a back-up in case of compatibility problems). I tried yesterday to upgrade to Ubuntu 12.04 via the update manager.
The upgrade appeared successful, but after rebooting the system as instructed to complete the upgrade, an Ubuntu screen appeared with the error message "Disc drive for / is not ready yet or not present", with the options to wait, press S to skip or M to manually recover.
This screen did not change after leaving the computer for several hours. After switching off and restarting, the same message appeared. I found the skip option gave a similar message about the disc drive for /tmp: Skipping this as well gave a black screen showing just a flashing cursor.
Switching off and starting again, then selecting manual recovery led to a screen showing:
Root filesystem check failed.
A maintenance shell will now be started.
CONTROL-D will terminate this shell and reboot the system.

Discussions of similar problems on the Ubuntu forums recommended making sure the disc drive was mounted in read-write configuration by running mount -n -o remount,rw /, followed by dpkg --configure -a to finish the upgrade properly. Trying to manually recover following that method has given me the following:
Root filesystem check failed.
A maintenance shell will now be started.
CONTROL-D will terminate this shell and reboot the system.

I have tonight downloaded Ubuntu 12.04 from the Ubuntu website to CD (using a borrowed laptop), to re-install from scratch. However, my computer is now attempting to boot 10.04 from the hard disc (with the results above) even when booting from CD is selected.
Windows Vista does still appear to start up successfully from the hard disk, when selected.
I would appreciate any help you can give to solve this - my laptop is effectively unusable at present.
Many thanks in advance.
