[SOLVED]grub doesn't load after system upgrade

Hi guys, something like 12 hours ago I did a "pacman -Syu" and this morning when I turned on my laptop the only thing it displayed is the word "GRUB" on the top right corner of the display and then it freeze, it doesn't load neither the grub menu...

The last full system upgrade was some day ago, but yesterday it updates the kernel so I think that is the problem. I only have Arch 32bit on my pc, a partition for /boot, one for / , one for /home and a swap space.

Any idea?

here is my menu.lst

# (0) Arch Linux
title  Arch Linux
root   (hd0,0)
kernel /vmlinuz26 root=/dev/disk/by-uuid/738c6478-7f1d-4a86-a206-dbbd7008d60d ro
initrd /kernel26.img

# (1) Arch Linux
title  Arch Linux Fallback
root   (hd0,0)
kernel /vmlinuz26 root=/dev/disk/by-uuid/738c6478-7f1d-4a86-a206-dbbd7008d60d ro
initrd /kernel26-fallback.img

Re: [SOLVED]grub doesn't load after system upgrade

Do you make it to the GRUB menu, and if so, does fallback work?

argh sorry, you said you can't reach grub menu already. weird, I can't think of anything breaking your grub installation with a -Syu. You could boot from a live medium and just re-install grub..

you don't even get to the grub prompt where you can enter manually the boot parameters?

In the case of the above you could try chrooting into your install from a livecd and doing a grub-install from there, or directly from the arch install cd should work as well I suppose if you mount the correct directories.

not sure if you need to --bind more, but at least you should bind the following before chrooting

        mount --bind /dev /mountpoint/dev

You need to mount some directories before chrooting:

# mount -t proc none /mnt/proc
# mount -t sysfs none /mnt/sys
# mount --bind /dev /mnt/dev
