Grub2 Commands not found

zackf · #1 18th April 2009, 06:06 AM

So I have been exploring trying to boot from a grub like experience on a LUKS encrypted F10 drive, to my slave drive Windows XP fully encrypted with Truecrypt and have found no real way to do it yet.

I did a yum install grub2 and have been playing with it (grub now has an option to boot to grub2 - on the unencrypted /boot partition which grub4dos was not able to do - or at least I was not able to make it do it).

to chainload I add

Code:

insmod chain

to the top which eliminates the

Code:

 "chainloader: command not found"

error I was getting

This is my grub2.cfg exactly for the Windows Part which I copied almost directly from a site that I have never been to or heard of but "reported" it to possibly maybe work:

Code:

menuentry "Microsoft Windows XP" {
        set root=(hd1,1)
        makeactive
        rootnoverify(hd1,1)
        map (hd1,1) (hd0,1)
        map (hd0,1) (hd1,1)
        chainloader +1
}

I have been advised the makeactive is probably not necessary but now I am getting this:

Code:

map: error command not found

But there is no module to insert to "map" - and that notwithstanding I don't even know if it'll work, but I was once told you could do anything in Linux - we'll see about that.

I'd try taking out everything but

title
rootnoverify (hd1,1)
chainloader +1

and see if that helps.

It brings up an

Code:

error: invalid signature

It looks like there are a lot of bugs involving that with grub2 but they all seem to be from a long time ago. ah well. It was worth a shot.
