[Solved] Grub Error 13, ext4 and 2.6.28.1

Hi guys!!!

I have formatted my laptop disk in new ext4 format, following wiki instructions:
http://wiki.archlinux.org/index.php/Cre … _Partition

and all wok fine.

But after today update (pacman -Syu), my arch don't boot.

Grub messages (lastest grub version, normal grub no grub2):

Filesystem type is ext2fs, partition type 0x83
kernel /boot/vmlinuz26 root=/dev/disk/by-uuid/.............
Error 13: invalid or unsupported executable format

No Normal image nor Fallback image boot.

Any suggestion?

P.D. Sorry for my englis xD

Re: [Solved] Grub Error 13, ext4 and 2.6.28.1

from grub's web site:

13 : Invalid or unsupported executable format
    This error is returned if the kernel image being loaded is not recognized as Multiboot or one of the supported native formats (Linux zImage or bzImage, FreeBSD, or NetBSD).

I think your vmlinuz26 file is wrong in some ways, or grub can't read ext4 correctly (I have done a fresh install with ext4, but I have made a separate partition for /boot in ext2)

following wiki instructions:
http://wiki.archlinux.org/index.php/Cre … _Partition

did you create from scratch or did you convert from ext3 ?

Basically, you need reinstall grub on MBR.
Download the chaox-ng live-cd: http://jenux.homelinux.org/~jens/livecd … -21-04.iso
On chaox-ng grub, enter in shell mode. Run the following commands:

mount /dev/sda1 /mnt
grub-install --root-directory=/mnt --recheck /dev/sda

replacing sda1 for your root partition and sda for you primary hd boot.
Reboot.

Wow... Thanks muchly. Quite the scare this morning when I, too, encountered this error.

It wasn't enough to simply mount my root partition, though--I needed to follow all the steps here first, then run 'grub-install --recheck /dev/sda'. Of course, I used SystemRescueCd, which may account for the difference.

I've updated the ext4 wiki page to document the solution to this error.

Thanks!!

Reboot.

With this steps (and the pointone's instructions) my arch boot again.

Thanks.
