XP boot partition
 

how do i check what partition my XP boots off. my ubuntu boots from hd0,1 but how do i check that for XP?

I believe XP uses the MBR (can someone confirm this?).

If you want to know what partition it's using do an
... and you should see an NTFS partition somewhere.

Hope this helps.

thanks i'll try that.

the response i get is Cannot open /dev/sda?

did you run the command as root?

or

sudo fdisk -l worked and showed me its in /dev/sda2. now how do i add that to my grub menu so i can boot XP from grub? any ideas?

A quick search on the net or in the grub man pages should show how to boot a windows box.

As for sda2...

Grub sees sda as hd0 and starts counting partitions starting with 0 so:
sda2 should be hd0,1.

still not working. im getting Error 21: selected disk does not exist

Please post the relevant sections of /boot/grub/menu.lst

With Windows on the 2nd partition of drive 1, it might look something like this:

title Windows
root (hd0,1)
map (hd0,0) (hd0,1)
map (hd0,1) (hd0,0)
chainloader +1
makeactive
boot

The "map" tricks Windows into thinking that it is on the first partition on the first drive. Typical Google searches only discuss mapping whole drives.

The "booting" link below in my sig might help--at the end there is a link to a post by Saikee (the world expert)

title Windows XP
root (hd0,0)
savedefault
makeactive
map (hd0) (hd1)
map (hd1) (hd0)
chainloader +1
boot

do i need to change anything there?

i just tried editing the /boot/grub/menu.lst with
title Windows XP
root (hd0,1)
chainloader +1
makeactive
boot

and it works. thanks for your help guys.

You are mapping drive 1 to drive 2, but you said that you had Windows on drive 1, partition #2.

Look at my example, and the links

The map command is admittedly a bit confusing. Here is a link I found with an example:

They put the "root" statement after the "map", so the syntax is a bit different.
