Upgrade to 10.10 massively screwed up

[cnidus]

A power failure interrupted my upgrade from 10.04 to 10.10. I don't know exactly where in the process it happened. The upgrade was running overnight. Now, the machine hangs in the midst of booting. I have access to GRUB and can select among two kernels and the two associated recovery modes, none of which are Maverick kernels. Using recovery mode, I can see that the last error is:

mount: according to mtab, none is already mounted on /lib/init/rw
mountall: mount /lib/init/rm [123] terminated with status 1

The system does not drop to a maintenance shell as expected. And here is the fun part, there is no CD drive and the system will not boot from a USB, so I can't even do a clean install. I have an ethernet card that works. What are my options?

Is there a way to force it to drop to a maintenance shell? Failing that what can I do from an initramfs prompt correct/fix the upgrade?

You could try a network install

I kinda of figured it would be a netboot kind of thing....

I was hoping for a little detail...

How do I get the network card up and running so that I can download/communicate with the outside world?

This should contain all of the information that you need. If not, just google the answers. If you have an ethernet port on your comp or a non-wireless network card plus a spare computer then this should all be easy.

Best of luck.

Hi

I'm new to the forum but I've been an Ubuntu user for quite some time now. Instead of creating a new thread I thought I'd just borrow this thread since the title clearly explains my problem. I was upgrading my 10.04 to 10.10 last night, while it was installing I had to go somewhere urgently so I had to pack up my laptop, thinking it would suspend operations and it can continue where it left off at a later time. So when I got home, I setup my laptop hoping to see Ubuntu restore itself but to my surprise my laptop had shutdown. I tried to boot to Ubuntu but now I can't get past the loading screen and the usual Ubuntu logo had been replaced with "10.04" in text. It was stupid of me to interrupt the upgrade but is there a way for restart the upgrade process? Recover mode does not work either. I can still boot to grub though from the bootloader.

Any help would be greatly appreciated.
