Wubi installer is a great little app for installing Ubuntu just like it was a program instead of an operating system. You don’t have to do any partitioning and you don’t have to worry about breaking Windows. This tutorial takes you from downloading Wubi to the desktop of Xubuntu (the process is the same for Ubuntu).
