In this section, I am going to show you how to install Ubuntu Desktop 20.04 LTS on a VirtualBox VM.
If you want to install Ubuntu Server 20.04 LTS, the installation process will be a little bit different as Ubuntu Server 20.04 LTS uses a terminal based installer. If you need any assistance on that, check my article Installing Ubuntu Server 20.04 LTS at LinuxHint.com.
Now, click on Install Ubuntu.
Now, select your Keyboard Layout and click on Continue.
From here, you can do a Normal installation or Minimal installation.
Normal installation comes with all the apps as usual.
Minimal installation comes with a limited number of apps. It saves a lot of disk spaces.
If you have internet connection on your computer, you can check Download updates while installing Ubuntu to download all the necessary updates while installing Ubuntu on your computer.
Once you’re done, click on Continue.
As this is a VM, I won’t go through the trouble of manually partitioning the hard drive. Just select Erase disk and install Ubuntu and click on Install Now. The Ubuntu installer will automatically create all the necessary partitions in your virtual hard drive.
If you need to do manual partitioning, check my article Installing Ubuntu Desktop 20.04 LTS at LinuxHint.com.
Now, click on Continue to write the partition changes to the disk.
Now, select your time zone and click on Continue.
Now, type in your personal information and click on Continue.

Once the installation is complete, click on Restart Now.
Once you see this window, press <Enter>. The VM should reboot.
Once the VM boots, you should see the following GRUB menu. Select Ubuntu and press <Enter>.
You should see the Ubuntu Desktop 20.04 LTS login window. Now, you can log in using the password you’ve set during the installation.
Once you log in, you should be able to use Ubuntu Desktop 20.04 LTS as usual.
