[ubuntu] Grub error 12 question [Archive]

A quick question: -

I have windows XP installed on the Primary Hard Drive, which has two partitions: c: and d:

I then have ubuntu installed on a second (slave) hard drive, which also has two partitions: the main one and then the swap partition (sorry, don't know the correct terminology).

When recreating grub after a re-install of XP, what would I enter for X and Y in this string: -

grub> root (hdX,Y)

and also, does this string remain as: -

grub> setup (hd0)

Just trying to recreate the grub loader but getting an error 12 message and I believe I entered the wrong values.

The code comes from this guide - https://help.ubuntu.com/community/RecoveringUbuntuAfterInstallingWindows - which I followed last night and I thought had worked.

The X and Y where is root.
after you find /boot/grub/stage1,
the root must be seen.that's the (hdx,y)

Sorry Frozie - don't understand what that means :confused:

I have attempted to recreate Grub again and when I run
find /boot/grub/stage1 I get (hd1,0). I then do
root (hd1,0)

For
setup (hd0) I have tried both (hd0) and (hd1) but I still get the same error message.

Looking at the windows stanza in /boot/grub/menu.lst, I have this: -

# This entry automatically added by the Debian installer for a non-linux OS
# on /dev/hda1
title Microsoft Windows XP Professional
root (hd0,0)
savedefault
makeactive
chainloader +1

The root entry here is (hd0,0) - is that the problem?

I think it would help to get a clearer picture of your setup, so how about downloading the Boot Info Script to your Ubuntu desktop (can be a Live CD):

https://sourceforge.net/projects/bootinfoscript/

Then open a terminal (Applications > Accessories > Terminal) and do:

sudo bash ~/Desktop/boot_info_script*.sh
That will create a "RESULTS.txt" file in the same directory from where the script is run, namely your desktop; please copy/paste the contents of the RESULTS.txt file to your next post.

hi cal, the results reads as follows :-

It looks like you installed Windows to sda5, but Windows' boot files are in the sda2 partition. Therefore, how about trying:

title Microsoft Windows XP Professional
root (hd0,1)
savedefault
makeactive
chainloader +1
Let me know if that works OK or not.
