Dual boot(2 hd's)windows + debian

[tombs]

Please, I have 2 hd's . The master hd has debian sarge and the slave WindowsXP. I tried to make the dual boot possible, but it didn't work out...including loosing grub. Now is fine, but I cannot boot windows. (Debian was instaled first). I have no idea of what to do now. Here I show my /boot/grub/menu.lst:
title Debian GNU/Linux, kernel 2.6.8-2-386
root (hd0,0)
kernel /vmlinuz-2.6.8-2-386 root=/dev/hda6 ro
initrd /initrd.img-2.6.8-2-386
savedefault
boot

title Debian GNU/Linux, kernel 2.6.8-2-386 (recovery mode)
root (hd0,0)
kernel /vmlinuz-2.6.8-2-386 root=/dev/hda6 ro single
initrd /initrd.img-2.6.8-2-386
savedefault
boot

### 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/hdb1
title Windows XP
unhide (hd1,0)
hide (hd0,0)

the best way is to install windows first. the problem is that debian isnt on the MBR. you need to install GRUB or LILO again.

I did it already, because I also "lost" my grub. But even so, I cannot boot the second OS.

Windows needs to be on the master drive.
You can either change the jumpers and ide cable.
Or you can "map" it so Windows will think t is in the master drive.

Do "info grub" in a terminal, look for the chapter that tells about booting other OS's and then look for how to map it.
