Tutorial: Ubuntu 20.04 LTS Desktop Linux Installation

In this tutorial, we cover the step-by-step installation of the freshly released long-term support desktop edition of Ubuntu 20.04 Linux.

The installation of other ‘buntu versions will be very similar. We will try to explain certain options and provide helpful hints along the way, so rather than just following the tutorial, you can understand the reasoning behind the decisions.

Every attempt has been made to ensure this guide is as accurate as possible, but please contact me to let me know if you find any errors. Please have a read of our disclaimer before proceeding any further.

Step 1:
The first thing you should do is head to the Ubuntu website and download the Ubuntu 20.04 LTS Desktop image by clicking on the green download box.

 

Step 2:
Using your disc burning software, burn the .iso you downloaded to a DVD.

 

Step 3:
Before you go any further, ensure all important data is backed up in case of data loss on your drives. This guide assumes you have media backups of your hard drives and you are safe to proceed.

Warning: Installing another operating system without first ensuring you have backups of your current files and operating system is a big risk. If you have no data to lose or you’ve backed up important data, you’re ready to proceed. YOU are responsible if you lose data.

For those of you using Windows and installing Linux for the first time I recommend you either use a separate hard disk not used with Windows or create a partition big enough for Linux within Windows, by using the Disk Management utility in the Administrative Tools menu of the control panel. 20GB of hard disk space is plenty of space for you to begin exploring Ubuntu Linux whilst at the same time having room to grow.

 

Step 4:
Ensure you have a network cable connected, restart your computer, and boot from the DVD drive.

At the first prompt, choose the first option, Ubuntu.

Step 7:
At the next prompt, we need to choose the options for updates and other software.

I recommend you select the option to install third-party software as this will ensure relevant graphics and Wi-Fi drivers are installed during the installation of Ubuntu 20.04. You can also choose to include any updates as part of the installation process.

Select the necessary options and click on continue to proceed to the next step.

You can opt to have Ubuntu 20.04 automatically log in for you — even with a password set — or you can choose the traditional option requiring a password to log in. You don’t need to choose the encrypt option unless you’re installing on a laptop and/or are dealing with highly secure information.

The installer will now finish off with installing Ubuntu 20.04 LTS.
