Grub Boot Error 24 on boot up

[daml]

First off, I am new to Ubuntu and Linux and i'm sick of windows and the constant BS it tends to offer so with that said,

I've been running version 9.10 for about 2 weeks now, this forum has helped me get a lot of my hardware devices working but this one is stumping me. When i boot this pc (Homemade) it get's a Grub Boot Error # 24. after searching some on the forum's i found and typed the following command into terminal and recieved the following:

ubuntu@ubuntu:~$ dmesg | tail

[ 1329.591657] EXT3-fs: group descriptors corrupted! 

What does this mean and how can i fix it?!

[ 1329.591657] EXT3-fs: group descriptors corrupted! 

I'm currently running from the CDrom so needless to say the OS is non-functional!
Also, Windows IS NOT installed as a second OS for dual boot.


Any and all help is appreciated!

Thanks!

I don't remember if the disk utility is on the livecd. You can use gparted as well.

launch the app, select the bad partition, perform a "check"


I'm sure there's a cmd line for it, but I don't know it.

This is the command line change sdb1 to what ever partition you want:

From liveCD so everything is unmounted
sudo e2fsck -C0 -p -f -v /dev/sdb1
if errors:
sudo e2fsck -f -y -v /dev/sdb1


If you want to know the parameters run this:
man e2fsck

Thanks OldFred,
That fixed it. i was hoping there was a check disk utility i could run but i didn't know the command or if it would even work from the CD-rom.

I'll be sure to keep this command handy as it should come in handy later on down the road. Thanks Again!!
