duel booting windows ontop of Ubuntu 10.10

[screw_ball69]

I've found tons of tutorials on how to duel boot Ubuntu with Windows already being installed but not the other way around, any help would be appreciated.

Hi and welcome to the forums :-)

First, backup all important data.

Second, partition the drive from the Ubuntu CD using GParted but do not format.

Third, install Windows to the unallocated space.

Fourth, reinstall GRUB to allow dual-booting.
