Upgrade interrupted now ubuntu isn't working

[tank.tmt]

Hello,

I was updating to the latest version of Ubuntu (i think 11.04) and the computer was restarted with 7 mins to go; my windows is still working on the same machine which means the booter is, but I cannot get into ubuntu.

Is there a way to recover functionality to ubuntu with doing a complete reinstall: aka keep my data?

you have several choices:

1) try to repair: boot in recovery mode from grub menu, then choose "repair" packages"
note: actually the servers are very busy due to too many download for installing/upgrading natty, so better to wait till next week.

2) reinstalling maverick if you still have its iso on your hdd
note: your data are safe if you use a /home partition

this is how a standard installation is done:

Can you access a recovery terminal? Look for recovery options in the GRUB menu (may have to tap shift or esc during bootup).

If you can reach a recovery terminal, please see this thread Hardy is wonderful (http://ubuntuforums.org/showthread.php?t=780531) for advice on how to recover from an interrupted upgrade.

Please post back here if you have problems with this advice.

I tried using the original install disc i used which was 10.04 but it would let me install side by side or overwrite, not repair: it also said that the current installation is 11.04.

I tried using the recovery option but it didnt work so as the boot menu also had other recovery things there where the number was slightly lower i tried them.
the next one said when i selected it that the drive couldnt be found and to either wait, skip or mount; skipping didnt do anything, mounting took me to a command line; i tried entering the commands from the thread linked but it just told me that it wasn't writable or somesuch

When i try going into the proper desktop or the recovery both say something about some python failing or somesuch

Please boot back into the recovery terminal and choose "m" for manual recover. Then please post back the output from the following commands
cat /etc/fstab|grep -E UUID^
sudo blkid
mount

This will give essential information required to clear the drive not found error; subsequently you can recover the interrupted upgrade using the commands in the linked thread (Eg, dpkg --configure -a).
