Boot Up Error - plymouth main process (217) terminated with status 2

[Alexander_]

Hi guys!

I was minding my own business, when all of a sudden my laptop wouldn't boot up =O

I would get the following screen:

init: plymouth main process (217) terminated with status 2
exec: 11: mountall: Input/output error
init: mountall main process (221) terminated with status 2
init: plymouth-stop pre-start process (227) terminated with status 1
Filesystem check or mount failed.
A maintenance shell will now be started.
CONTROL-D will terminate this shell and continue booting after re-trying filesystems. Any further erros will be ignored

I have an older version of linux, i believe 9.04 and always refused to update anything

i found another forum post of someone who appeared to have a similar problem as me:
linuxquestions.org/questions/linux-software-2/boot-errors-855689/#post4222238

and tried

sudo mount /dev/sda1 /mnt

but got:

mount: /dev/sda1 already mounted or /mnt busy
mount: according to mtab, /dev/sda1 is mounted on /

Are there any kind and knowledgeable people out there who can help? i hope i don't lose my files

Okay so I don't really know the solution to this, but i figured out how save my files.

I just loaded the install cd live, then was able to see my hard drive. However some folders were "Permission Denied" b/c I was not the owner =O

But then i typed "gksudo nautilus" into the terminal, and i got around the "Permission Denied"

I'm such a badass hacker!
