Hey. Well the problem is that your Ubuntu's boot loader [grub] is overtaken by windows boot loader and your ubuntu already exists. If you have no important data in ubuntu do this : Boot from ubuntu cd, install ubuntu in the same partition in which you installed it before installing windows. Just make sure you don't touch windows partition. After ubuntu is installed, it will automatically detect the presence of windows and will create a boot entry in grub for it. Reboot to check if you have windows option in grub boot menu...

Hey guys!
This is possible and for real... As smirnoff said... all the game is about the boot loaders... Well follow the steps:
Install Windows 7 in a seperate partition
This will eat up your Grub boot loader which is used by Ubuntu linux
Now boot from Ubuntu's live CD and just boot don't install it.
