First, BACK UP YOUR DATA.
Next, boot from an Ubuntu live CD. Open GParted, shrink the Ubuntu partition to make some extra unallocated space on the drive, and create a new NTFS partition in the empty space. When you install Windows, be sure to specify to install on that partition (do not just let it install wherever/however it chooses).
AFAIK this should work; but I haven't installed Windows in ages.
