GRUB ERROR 24, HELP PLEASE

[67GTA]

Error 24 usually means a corrupt file system on the disk, or a hard drive going bad. You can use a live CD to do a e2fsck check on your file system. If your lucky, it will find and correct some file system errors and boot just fine afterwards. Open a terminal and run

Code: Select all

sudo fdisk -l

. Find your Linux partition. It will be something like /dev/sdax, or /dev/hdax. Replace "x" with the Linux partition number. Write that down, and boot your live CD. Open a terminal, and run sudo e2fsck /dev/sdax, or /dev/hdax (which ever applies to you). Let it run, and hopefully it will show it fixed some file system errors. Here is the output of

Code: Select all

sudo fdisk -l

on my HD:

Device Boot Start End Blocks Id System
/dev/sda1 * 1 12748 102398278+ 7 HPFS/NTFS

sda1 is NTFS(windows) sda2 is Mint sda3 is linux swap sda4 is Ubuntu If I wanted to run a check on Ubuntu, I would boot a live CD(never run e2fsck on a mounted system, hence the live CD) and run

Code: Select all

sudo e2fsck /dev/sda4

. I hope that makes sense. e2fsck is essentially the same as doing a file system check on a Windows drive.

If you were booted into Mint, you wouldn't want to run the e2fsck check on it because the partition you are using is mounted. If you boot into a live CD, the partition you are running the check on is not being used, so it is safe. e2fsck will try to correct file system errors, which can screw up a file system while it is in use.
