    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!

  6. 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. :blink:

    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.
