    Angry cannot boot into ubuntu 11.10, cannot mount filesystem

    O.K, so this was a hellish day for me. I was running updates and there was power faliure (my ups is pretty messed up). so i re-booted in and ran
    Code:
    sudo dpkg --configure -a
    as i always do to resume updates. But then again, right as i hit return, there was power faliure.
    when i rebooted again, i had the grub screen with several options, i chose the top one(not recovery mode) and it took me to BusyBox inramfs or something like that.
    all this time the caps-lock and num-lock indicators were blinking.

    now i can't boot into my OS. I have only ubuntu 11.10 installed and only have one partition of the filesystem apart from swap.

    when i boot from livecd and try to mount the filesystem, it shows :
    Code:
    mount: wrong fs type, bad option, bad superblock on /dev/sda1,
           missing codepage or helper program, or other error
           In some cases useful info is found in syslog - try
           dmesg | tail  or so
    Code:
    dmesg | tail
    gives following result :

    Code:
    ubuntu@ubuntu:~$ dmesg | tail

    trying to mount from terminal gives :
    Code:
    ubuntu@ubuntu:~$ sudo mount /dev/sda1
    mount: can't find /dev/sda1 in /etc/fstab or /etc/mtab
    i dont want to reinstall and lose thousands of MB of data...is there a way out of this?

    Hi,
    just to make sure we know where everything is on the system, please post the results of the boot info script.

    There is a link at the bottom of my post with instructions.

    Thanks.

    Boot script should show us which partitions have issues or may show something else.

    But if system is writing in the middle of a power failure, you need to run filechecks.

    #From liveCD so everything is unmounted,swap off if necessary, change example shown with sdb1 to your partition(s)
    #e2fsck is used to check the ext2/ext3/ext4 family of file systems.
    sudo e2fsck -C0 -p -f -v /dev/sdb1
    #if errors:
    sudo e2fsck -f -y -v /dev/sdb1
    For info on UEFI boot install & repair:
