I have purchased a Dell laptop with Ubuntu Linux 12.04 installed in it, and I want to install Microsoft Windows operating system on Ubuntu and have dual booting. I hope to install the Microsoft Windows OS into a different drive than the one where Ubuntu is already installed. For example  if we have Ubuntu operating system in the the first drive, then I want to install Microsoft Windows Operating System in the second. I don't want to uninstall Ubuntu.
