Wine is a program that will help you to run Windows programs on Linux or in this case Ubuntu. Wine is not perfect and not all Windows programs will work with Wine. This tutorial will show you how to install Wine on Ubuntu 13.04.
Virtualbox is a program that allows you to install virtual operating systems inside a host system. In this tutorial I am going to show you how to install Virtualbox on Ubuntu 13.04 so that you can begin to test new operating systems inside Ubuntu without making permanent changes to your hard drive. In this tutorial we will be installing Virtualbox directly from the Virtualbox website rather than the Ubuntu repositories. The reason for this is the official version on the Virtualbox website included additional features like usb support.
