@ Felix i agree but was impossible for me to run update-grub because there was other errors when i try to do the update-grub on the chrooted mounted /dev/sda1 there are something wrong also in on the /boot/grub/device.map (it is empty) and i cannot create with sudo grub- mkdevicemap using the Ubuntu 8.10 live cd.
Now booting fine i was able to recreate the /boot/grub/device.map from the installed Ubuntu.
