Unable to boot after upgrade


Today morning I was upgrading ubuntu 10.10 to 11.04. When the packages were downloading it was showing 20m left to download. At that time I had a battery of 2 hrs. As I had to go so I left my laptop on and went( the charger unplugged ). When I came back I get the following message:

Code:

init:udevtrigger main process (546) terminated with status 1
init:udevtrigger post-stop process(549) terminated with status 1
The disk drive for / is not ready yet or not present
Continue to wait; or press S to skip mounting or M for manual recovery
init: udev monitor main process (545) killed by term signal.

I know this is coming because of improper shutdown. Also I think that the new ubuntu was not yet installed as in the boot menu it was showing old images only..

I had Widows 7 also. Thank god its fine so that I am able to ask question.

I am not a newbie but a little far from intermediate.

The installation has certainly been broken down by a power shortage.
For safety's sake you should have left the charger plugged.
Installing is an energy consuming process, and a current battery status does NOT predict the REAL time left for usage.

It's better to begin a fresh install now, forget about upgrading.
Make certain that you do not format partitions with data that was not yet backed up, such as your /home partition.
And last but not least, keep the charger plugged!

Good luck!

Thanks a lot. I had to go for about 6-7 hours and as far as I know over charging Li ion batteries decreases its life. So I took a risk and it didn't pay off.
As far as data was concerned I have already backup it using live USB. Yeah I will do a fresh installation but actually my main motive for posting was to learn about this as I am a Btech student and a lot of stress is given on Linux.
So still if there is something I can do to save or learn or even can know How and why this problem came, I would love to.

Thanks again.
