Hello

Sounds like a miss configuration to me (Probably not your fault, but of the installer itself^^). In order to analyze the problem, it would be very useful, if you could post your menu.lst. You can find it at /boot/grub/menu.lst.

Ah thanks man.to be honest didnt expect such a speedy reply. Was'nt sure if you wanted the whole
file but this starts from "## ## End Default Options ##" part:

hmm, unfortunately(;-)) your menu.lst seems to be correct. Could you please also post the output of sudo fdisk -l? This will help judging whether your partition table matches the entries in menu.lst.
However I personally believe that they will match. I don`t know in which order you installed windows and ubuntu on the harddrives, but considering your problem description I think the map-trick should solve the problem. This is necessary if the windows bootloader believes to be on the first harddisk, while being on the second. (for example because it was installed, when the second harddrive wasn`t in your computer, or if you rejumpert them). You can then simulate windows to be on the first using the map-trick. Just change your last part of menu.lst to

---------------------------------------------------
# This entry automatically added by the Debian installer for a non-linux OS
# on /dev/sda1
title Microsoft Windows XP Professional
rootnoverify (hd1,0)
map (hd1) (hd0)
map (hd0) (hd1)
savedefault
chainloader +1
------------------------------------------

This should do the trick. If it doesn`t then please provide the output of sudo fdisk -l and also the contents of the file /boot/grub/device.map

Have fun with a working dualboot (hopefully^^)
