Boot error whith Natty(Éditer)

I got the same error this past weekend all I did was boot from the live CD and chrooted my Natty / using the following commands:

• sudo mount /dev/sdXx /mnt
• sudo mount -o bind /dev /mnt/dev
• sudo mount -o bind /sys /mnt/sys
• sudo mount -o bind /proc /mnt/proc
• sudo chroot /mnt

Once at the prompt I reinstall grub:

• grub-install /dev/sda
• and then updated grub
• update-grub
• then Ctrl-D twice to exit, and reboot.

To set passwords for users from the command line, type:(Éditer)

chpasswd

Followed by entering username:password pairs, one pair per line. Enter CTRL+D when finished.

user1:passwd1

user2:passwd2

CTRL+D

~$ sudo chgpasswd root:***

CTRL-D
