All of a sudden Ubuntu is not booting anymore

What should I do?

 

drive seem gone. what utils/diagnostic tools do you have to fix the errors and salvage data?

 

Drive is ok as XP on another partition of same drive is booting fine. Data is not important and I have an image backed up few months backs but I was thinking it can be fixed!

 

Did you "fsck" as indicated?

Try this.

 

Boot from the Ubuntu CD in rescue mode as linuxforall state, then run as root 'e2fsck -f /dev/sda7'.

Also, get a backup hard drive.

 

Hi aigle,

Your screen shot looks like you do not have a /proc and maybe a /sys and probably a /home in the .iso image your are attempteing to boot from - if that is what you are indeed attempting to do. I say this from the experience of getting the same messages as your screen shot when I built a custom .iso image of Ubuntu 9.10 without /proc and /sys.

Otherwise, it looks like you do not have such directories in your installation and if you do check everything with a Live CD bootup and in fact do have those directories, then look at their privileges.

As Gullible Jones said, first boot into a livecd and run fsck as he illustrated. Then, if you are able to boot back into Ubuntu, the next thing you should do is:

Code:

sudo apt-get install smartmontools

After that install, then run:

Code:

smartctl --test=short /dev/sda

This will run a short test on the hard drive. After a few seconds, run:

Code:

sudo smartctl -H

This will give you the health status of your hard disk.

If you want a more in depth analysis, run a long test:

Code:

smartctl --test=long /dev/sda

Then run "sudo smartctl -H" again.

These tests should give you a good indication on whether it's time to replace the disk.

 

Hi, thanks all of you really. Sorry i could not respond as was really so busy.

I just tried fsck /dev/sda7 after the above screen. A couple of disk scan passes and a couple of questions, I replied Yes to all and now it,s all OK. File system fixed. Also the disk is healthy.

BTW I have no Grun installed as I am dual booting Ubuntu and XP with Comodo Time Machine installed in windows MBR. I boot linux partitions via Super Grub Disk CD.
