====== Ubuntu - Grub - Password Protect Grub Bootloader ======

<code bash>
sudo grub
</code>

----

At the "grub>" prompt type md5crypt:

<code grub>
grub> md5crypt
</code>

----

Enter a password at the Password: prompt, preferably something other than root password:

<code grub>
Password: *****
</code>

----

It will then give you the password encrypted:

<code>
Encrypted: $1$Rdv455345ga345GvIRgXWxcF1Vjb7tZ//
</code>

----

Copy the encrypted password into the clipboard.

----

Edit **/boot/grub/menu.lst**:

<code bash>
vi /boot/grub/menu.lst
</code>

After you see title SUSE Linux 10.0 on the next line type lock.

On the following line type password md5 [the encrypted password you copied from previous shell]:

<file bash /boot/grub/menu.lst>
