[ale] Windows restore partitions

[Brian MacLeod]

I'll assume grub as that is the usual default boot loader:

Get a md5 hash of the password you would like.  One way to get it is to ask
grub on its command line to give it to you:

grub> md5crypt

Not that useful unless you write it down from here.

Or from the linux command line (as root on NON-Ubuntu systems, or as regular
user on Ubuntu):

$ grub-md5-crypt

Which you can redirect to wherever you need to make it easy for you to put
into the configuration file (usually /boot/grub/menu.lst)

For accessing grub command line, editing options, and any entry protected by
keyword "lock" (in the boot entry) specify the following line BEFORE any and
all TITLE lines:

password --md5 MD%ENCRYPTEDLINE

If you wish to have a specific password for an entry, outside of the above,
put a similar line with a different md5 hash IN a boot entry (after a TITLE
line).
