Whether you want to Install Ubuntu within Windows/Mac or install another OS within Ubuntu this guide will show you how to prepare VirtualBox for a Virtual Installation.

You will need:

An Operating System ISO file or Disk, if you don't have either Download a Ubuntu ISO

Preparing VirtualBox

  1. Open VirtualBox and you should see a screen similar to this:

    (Note: My host OS is Ubuntu, on a different OS it may look a little different - This goes for all screen shots here in)

  2. Next click on the 'New' button, a window will appear, click 'Next'. Then you will see a window like below, Enter in a name for your OS, Select Linux For the Operating System and click next. (Ubuntu is the default setting for Version, if you will be installing Ubuntu 64 bit you can select it from the drop down)

    (Note: If you wish to install a different OS select the relevant 'Operating System' & 'Version' options from the drop down menus. A list of all supported OS types can be found below.
