Virtualisation has changed the way many people interact with computers. Using a virtual machine such as Sun's free and open source VirtualBox, a user can run multiple instances of different guest operating systems from a single host machine, increasing a single installation's potential exponentially. VirtualBox allows for a number of settings to be specified beforehand, including boot order, hardware types and many other options that would normally be set by the BIOS. These settings act as the BIOS normally would for a host machine.

Skill level:
Moderately Easy


  1. 1

    Launch VirtualBox from your "Programs" menu.

  2. 2

    Select the virtual machine you wish to edit, then click the "Settings" button to bring up the dialogue.

  3. 3

    Click the "System" section. Here you can change boot order, like you would in a host machine's BIOS, along with CPU settings.

  4. 4

    Click the "Display" section. You can enable or disable graphical acceleration and limit the amount of graphics memory in this section. You actually have more control over how your virtual machine functions than a host BIOS would normally give you.

  5. 5

    Click the "Storage" section. You can edit your hard disk controllers in this section, creating extra virtual hard drives if you need expanded storage.

  6. 6

    Click the "Network" section. In the Networks section, you can edit your network adaptors, enabling or disabling various features as you would in a host machine's BIOS.
