If you want to change your current windows desktop/laptop to dual boot with an option of Ubuntu, Wubi is the recommended way to go. Wubi stands for Windows Ubuntu Installer which helps to install Ubuntu just like you would have installed any other application on your Windows machine.

However, today….. Read More
