1. Obtain a copy of windows 7.
*You can also find a torrent of this but for legal reasons I cannot provide
a link. *
2. Partition your disk
This does go wrong in some cases, if in doubt back up your valuable data.
Boot from a Ubuntu live cd or a
gparted live cd. Start up gparted, If
ubuntu is on the whole disk you need

Follow the on screen instructions,
Select the un-partitioned space to

you already made it NTFS choose your
It will ask for a product key but you have 30 days to do that. Note:

grub> root (hdX,Y) grub> setup (hd0)
(you don’t need to type the grub> bit)

no longer see windows7
5. Edit grub. Go to terminal from normal ubuntu and type :
“sudo gedit /boot/grub/menu.lst”
A large text file will open and at the
bottom leave a line and add this:
title windows 7 beta (Loader) root
(hd0,1) savedefault makeactive
