Comment 8 for bug 700910

I forgot to add the following informations :
root@ubuntu:~# dpkg -l|grep grub
ii grub-common 1.99~rc1-13ubuntu3 GRand Unified Bootloader, version 2 (common files)
ii grub-gfxpayload-lists 0.2 GRUB gfxpayload blacklist
ii grub-pc 1.99~rc1-13ubuntu3 GRand Unified Bootloader, version 2 (PC/BIOS version)

Also, I tried to fix the unbootable netbook problem with chroot :
root@ubuntu:~# mount -o bind /proc /mnt/linux/proc/
root@ubuntu:~# mount -o bind /dev /mnt/linux/dev/
root@ubuntu:~# chroot /mnt/linux/ /bin/bash
ubuntu:/# update-grub

done

I'll reboot to see if this worked.
