You should boot from a live CD/DVD and do an fsck on the file system on dm-0.

That didn't do anything.

From live i ran fdisk -l

returned:

What didn't do anything?

The live CD may use different names for the LVM volume groups and logical volumes. According to fdisk, you have two such volumes: /dev/mapper/VolGroup00-LogVol00 and /dev/mapper/VolGroup00-LogVol01.

From the size you should be able to determine which is the boot volume. Then run fsck on that volume.

I fsck the first vol but its mounted and wont run the check.

also using unbutu as my live.

I don't know why the Ubuntu DVD would mount a volume on your hard drive, but you should be able to unmount it with umount.

(I usually use System Rescue CD, and it doesn't mount anything unless I tell it to.)

thanks, currently running fsck ill update once done

Okay so one down.

So it still not booting but the lines say:

no fstab.sys,mounting internal defaults
Switching to new root and running init.
unmounting old /dev
unmounting old /proc
unmounting old /sys
/sbin/init: error while loading shared libraries: libsepol.so.1: cannot open shared object file: No such file or Directory
Kernel Panic - not syncing: Attempted to kill init!

Looks like your root file system has taken some serious damage.

I would suggest booting the live DVD again and mount the partition to a temporary directory to see just how bad it is. Perhaps the missing files and/or directories can be recovered from /lost+found.
