To install Ubuntu Server 20.04 on a VirtualBox virtual machine, follow the detailed steps below. These steps ensure VirtualBox is already installed.
Step 1 – Create a Virtual Machine:
– Launch VirtualBox and click on “New”

Select an amount of RAM: Assign memory to your virtual machine.
– I will select 2048 MB
You can increate the memory with the slider or by typing the values.
Create your virtual machine’s virtual hard drive. The virtual hard drive is a section of your computer’s hard drive space which will be used to store your virtual machine’s files etc.
This will open the Hard disk type window. I will be selecting VDI (VirtualBox Disk Image) as shown below. For the differences, take a look on how to install VirtualBox and Guest Integration.
You can choose either the “Dynamically allocated” or the “Fixed size” option for creating the virtual hard disk. I will be choosing the “Dynamically allocated” as shown below. For the difference, Please see the screenshot.
Enter the desired file location and size of the VDI. You can use the slider or type the size into the field as shown below.
– Click on create and VirtualBox will generate the “Ubuntu” virtual machine.
Step 2: Now the virtual machine is created. We are ready to install Ubuntu in this virtual machine. It is time to boot that ISO and install Linux as a virtual operating system.
The next steps requires Ubuntu 20.04 to be downloaded, see this link.
Select your new virtual machine and click the ‘Settings’ button.

The Ubuntu Desktop OS is ready. As you can see, the desktop screen is too small. To fix this the “VirtualBox Guest Additions” need to be installed.
