Dual boot with windows on a slave hd

Trying that may be is a pain in the ass. To avoid it, read below something that will help you.

First of all, I’ll tell you why the problem happens. When you install windows on a slave hd and wants to dual boot, windows thinks it’s on the master hd and won’t cooperate. What you have to do is fool windows so that it thinks that it is really on the master disk. So, tell the BIOS to remap the drives. How? Simple.

Edit your ‘/boot/grub/menu.lst’ so that it has the following lines (where you write down the windows stuff)

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

Windows is, in that case, on a ide slave disk and the master is a sata hd with debian lenny.

If running debian, do

# update-grub

Reboot and be happy! =D
