Installing VirtualBox Guest Editions

You may find that you are unable to get the virtual machine's display window in VirtualBox to take up the entirety of your host machine's screen. As a result, the content in the VirtualBox window may be hard to view due to the low resolution and relative size of the screen. To resolve this, we will need to install VirtualBox Guest Editions. This section will walk you through the process.
  1. Open the Oracle VM VirtualBox application.
  2. Click on Devices at the top of the screen to bring up a dropdown menu, then click Insert Guest Editions CD Image.

  3. Click the Run button on the popup window that appears.

  4. You will then be prompted to enter login password that was setup in the previous section. Enter it click and Authenticate.

  5. The installation of the VirtualBox Guest Editions will now begin. A terminal window will display the installation processes. Allow the installation to run until it finishes. When the installation is done, you should receive the message "Press Return to close this window." Press Enter/Return to close the terminal.

  6. The virtual machine must now be shutdown and restarted.
    1. Click the button in the lower lefthand corner of your virtual machine's desktop display.
    2. Click the button.
    3. Click Shutdown to turn off your virtual machine to return to the Oracle VM VirtualBox main menu.
