Grub password protect other OS

[soupisgood84]

Hello,
I am brand new to these forums. I did some searching around the net and was unable to find anything regarding this topic. I was wondering if there was a way to password protect the other OSs on my multi-boot system through the Fedora 10 Grub. I know you could protect them by placing password on the OSs themselves but I was just curious if the boot loader was able to do this for you.
Thanks for any info.

It appears to be possible, in a terminal type "info grub" (without the quotes of course). That gives you the full manual. Have a look at the security section. Haven't tried it but it may help others if you post your results back here.

from the command line .

Create an MD5 password hash for GRUB

#grub-md5-crypt
password:

Next, copy the hash output.

Then, open /boot/grub/menu.lst

add to the top...

password --md5 <paste your hash>

Then at the end of initrd on the next line add lock.

<example:>
initrd /initrd.img-2.6.8-2-k7
lock
<example:/>

reboot.

and lastly at GRUB slash page. press p to promt for password.

I just wanted to come back and let you guys know that this worked perfectly. I was trying to password protect all my OS's except one and was able to accomplish this. Thanks very much!
