Woke up to a terrible find yesterday, I couldn't boot into my laptop.

I have kubuntu/XP dual boot, all had been fine. My guess was the Kubuntu root partition has either reached or almost reaching its max space, 15G
I had installed 4 Linux Operating systems onto VirtualBox which must have done the job.

I now get a couple of errors on boot;

Problem loading please wait;
Error2
and

Error5

and an error of not finding the operating system.

I installed a Knoppix live cd that at the beginning read the different sda partitions but wouldn't allow me to edit them and then after rebooting, it stopped reading them.
GParted on Ubuntu Feisty live Cd read the partitions, and also told me that kubuntu root partition is at 13.79G, a little less than the max 15G.

What now, could this be a Grub problem?
How can I recover and fix it using a linux live Cd?
I dont have Sys Rescue Cd but maybe knoppix will do?
Would installing another Linux distro on a separate unallocated partition, with 9Gs of space, help in the recovery process?

all help extremely appreciated

Error 2 : Bad file or directory type
This error is returned if a file requested is not a regular file, but something like a symbolic link, directory, or FIFO.

Error 5 : Partition table invalid or corrupt
This error is returned if the sanity checks on the integrity of the partition table fail. This is a bad sign.

You probably want to lighten the load. Also try fschk

great link Simon Bridge thanks..

I had mentioned to my mentor and he referred me to executing fsck via the knoppix live cd

The process is taking a long time since it is about 14Gs of inodes to reorganize, if i understand correctly.

I do plan on getting some load off as soon as i can log into the partition, thanks.
