Help with GRUB

Can someone who is running GRUB on the MBR of their boot drive please post their /boot/grub/menu.lst. I am looking for a menu.lst that has an entry for the recovery partition, which I believe is called 'IBM Service partition' in the boot menu (or something like that). I am trying to recreate that boot entry which got lost the last time I installed Linux. Thanks!

none of my machines has anymore recovery partition, so I can't offer 100% positive answer.

but this looks right to me and is more or less what I was going to suggest off the top of my head before double checking vs google:
http://www.thinkwiki.org/wiki/Talk:Resc ... _from_GRUB

Code: Select all

parttype (hd0,1) 0x0b
title           IBM Rescue and Recovery
root            (hd0,1)
chainloader     +1

of course that assumes the service partition is 2nd on the disk (I think on my x61 it was actually first?! hd0,0) and that it is fat32 (type b; apparently this may be needed if r&r had set its partition to a fake/wrong type to prevent windows from seeing it) -- ymmv. also it can't hurt to use rootnoverify instead of just root, when dealing with windows.

tarvoke thanks. That entry boots into Vista, so it must fail then default into it. Here's some additional information;

in that case it seems mostl likely to be hd0,0 (since it has a weird type listed) ...or otherwise hd0,2

hd0,1 from your fdisk output, looks to be where vista lives.

Thanks, this worked -

title IBM Rescue and Recovery
rootnoverify (hd0,5)
chainloader (hd0,0)+1

Here is what my R61 has at the end of menu.lst:

Code: Select all

### END DEBIAN AUTOMAGIC KERNELS LIST

# This is a divider, added to separate the menu items below from the Debian
# ones.
title		Other operating systems:
root


This entry automatically added by the Debian installer for a non-linux OS
# on /dev/sda1
title		Thinkvantage Rescue & Reovery
root		(hd0,0)
savedefault
makeactive
chainloader	+1


# This entry automatically added by the Debian installer for a non-linux OS
# on /dev/sda2
title		Windows Vista Ultimate
root		(hd0,1)
savedefault

But I am running a ubuntu derivative.

Thanks Carbon_Unit. I think what you have in menu.lst and what I posted are functionally equivalent in GRUB.
