How to install Ubuntu 20.04 (with pictures)?

In this article, I will explain how to install Ubuntu 20.04 LTS on your device using a bootable USB drive and Ubuntu ISO file.

Ubuntu installation is very similar to Linux Mint installation as Linux MInt 20 is based on Ubuntu.

You can install Ubuntu using a bootable USB drive, but before we can start installing Ubuntu 20.04 LTS, we will need to download the required files and create a bootable USB drive.

Follow along this article to create and boot a live Ubuntu USB drive to install it easily.

To install Ubuntu you first need to download its ISO file by visiting Ubuntu official website.

Under downloads section you will find two Ubuntu versions. You need to download Ubuntu Desktop as this is the one that we will continue our installation with.

The download size will be around 2.7 gigabytes so consider downloading via torrent if your internet connection is slow or unstable.

2. Make Ubuntu live USB

Now, after downloading Ubuntu, the very next thing we need to do is to make a live USB so we can continue our installation.

If you are on Linux, then right click on the ISO file and choose “Make a bootable USB” option.
