Hey guys, I have a theorycraft type question.

Say I have this partition layout:

sda1 = windows 7 boot partition (that 100mb partition)
sda2 = windows 7 root partition
sda3 = linux /boot (bootable partition containing grub)
sda4 = linux root
(forget about swap)

Assuming /dev/sda3 is setup as the Bootable partition, when you're setting up grub.conf to dual boot, should you reference /dev/sda1 OR /dev/sda2?
In other words, should grub.conf contain this:

Code:
title Windows XP
rootnoverify (hd0,0)
makeactive
chainloader +1


OR

Code:
title Windows XP
rootnoverify (hd0,1)
makeactive
chainloader +1


As I understand it, you should reference /dev/sda1 (hd0,0) in grub, because that partition contains the code necessary to boot into the Windows root partition on /dev/sda2.
Is this understanding correct?

i think this is correct.

for testing you could write two different grub menu-entries with (hd0,0) and (hd0,1) and see what happens.
GOOD LUCK!
