Libreboot reinstall after a mistakenly typed command on TX200

Hello,

I've been working during days on the main entry of libreboot for a fresh install of Trisquel 8.0 reading manuals and examining the capabilities of the system.

By manipulating the command prompt trying to save energy as a main goal I lost precious data.

I shouldn't have worked that much on the added possibilities on a new entry to grub install. My live install is finally running it but nothing can - correct me if I'm wrong - reboot my system if I shut it down.

The MBR might be broken or totally corrupted.

The incriminated command is:

$ sudo -i
# chroot /dev/sda1 /mnt
# exit
# rm -rf /mnt
