Norman >>> This is the last section of my menu.lst

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

I've got Ubuntu on hd0 (the 'first' hard drive) and Windows is on hd1. 
Windows will refuse to boot if it isn't in the first partition of the 
first drive. That's why we trick windows to make it think it's there 
with the map lines, which remap the drive numbers for windows.

NB:  My "root" value - hd1,1 (not hd1,0) - is to jump over a small 
partition that Dell puts at the start of its drives to get to the main 
partition where Windows is.

Are you sure Windows is in the first partition of the drive it's on, and 
you don't need to jump over something?
