A Tutorial to Install Ubuntu on VirtualBox
- 1). Download and install the version of VirtualBox specific to the host OS (the operating system in which VirtualBox and Ubuntu will exist). Also download the latest copy of the Ubuntu distribution disk image; it will end with the ".iso" file extension. This file is necessary to install Ubuntu in VirtualBox.
- 2). Start VirtualBox. On the main screen, select the "New" icon to start the new OS installation process. Follow the Setup Wizard. Click "Next." The next screen requests the user to select the guest OS. Select "Ubuntu" from the drop-down list. Give the OS a name. Click "Next."
- 3). Select the RAM (Random Access Memory) allotted for the guest OS. Ubuntu requires a minimum of 512 MB. More will allow Ubuntu more room to run applications, but do not allot too much: RAM allotted to a running guest OS is not accessible by the host operating system, and system performance can suffer. Set the slider to either 512 MB or 1 GB (or more, if more resources are available). Click "Next."
- 4). Select "Create New Hard Disk." Click "Next." The virtual disk wizard will open in a separate window. Click "Next." The screen will ask you to create a fixed-size disk or an expanding disk. Make your choice. Click "Next." Select your storage size. Ubuntu requires at least 4GB to install; more should be allotted for programs and data. Click "Next." Review your requested disk specification. If correct, click "Finish." Wait for VirtualBox to create the disk.
- 5). Install the guest OS. Ubuntu will now be available in the left menu on the main screen. To the right, VirtualBox displays the OS details. Click on the "CD/DVD-ROM" listing. In the new window, look for the "CD/DVD-ROM Device" section. It should display an "Empty" listing next to it. Click the folder icon adjacent to the listing. Browse to and select the Ubuntu Image File (the .iso file). Click "OK." Now the Ubuntu image is loaded. Start the Ubuntu guest OS. Follow the installation wizard.
