what is the device name of his windows partition?  i have found a way to
mount windows partitions in linux at startup.

as root, gedit /etc/fstab.  add a line like this just before the swap line:

/dev/hda1               /win                    auto          
auto,user,exec,rw,async         0 0

create a folder named /win, and reboot. on the gnome desktop there
should be a drive with the title 'win'.  next, configure whatever you
need to run off /win.  This is how i manage windows files in linux.
