A month has passed since the launch of Ubuntu 20.04 LTS, the most important launch of this distribution for the next two years, as well as the recommended version for new installations in practically all use cases during said period of time. We have thoroughly tested it and we can assure that it is ready to produce, so we proceed to update our Ubuntu installation guide for those who may need it.

In this guide we explain the Ubuntu installation process step by step as concise and simple as possible, but trying to be meticulous, hence it may seem more complicated than it actually is: installing Ubuntu is quick and easy. In essence, this guide is identical for the most part to those we have published previously, since the Ubuntu installation process has hardly changed except in specific points. The intention, then, is to update the content for the new version of Ubuntu.

Before starting, we recommend you read carefully:

Previous considerations, where we gather several things that you should take into account before installing Ubuntu, including the possibility of trying it without installing it, the estimated requirements or the recording of the installation image, among others.Ubuntu 20.04 LTS release announcement, where we summarize the news of this version and where you will find the links to access the download of the installation images.

And one more thing: remember to do back up your data before anything. Prevention is better than cure and either because you are going to make changes to the system – regardless of the system you use – or because it may fail you at any given time, backups never hurt.

If you already have everything ready, we start with the installation of Ubuntu.

Keep in mind:

The Ubuntu system installer may differ slightly depending on the edition, but the process is broadly the same, even if another system installer is used, such as Lubuntu. However, the steps and images in this guide correspond to the installation process of Ubuntu 20.04 LTS, the main edition with the GNOME desktop. Being connected to a power outlet if you install on a laptop is not essential if you have The battery is charged, but it is recommended: if the battery runs out before finishing, you will have to start from the beginning.

1. Language selection / Install or test?

Nothing else to start, pressing F2, you can choose the language and directly start the test or installation of the system, among other options. However, this is a step that you can skip because as you load the installer the same options will be offered. It is displayed in case you run into any problems, in which case you can start with the “safe graph mode” options.

Be that as it may, the previous screen lasts only a few moments and then a check of the installation medium is carried out, which will not last much longer either.

Shortly thereafter (how late it will depend on your equipment) the first screen of the system installer will appear, where you can choose the language. If you have done the previous step, this is already done. Ubuntu offers the possibility to test the system without installing it on disk and without affecting any other operating system that you have installed.

If you choose to try Ubuntu, the desktop will start, from where you can continue the installation (we have done so for this guide in order to show better images).

2. Configure the network

When installing Ubuntu on a PC that only has a wireless connection, the next step is setting up a Wi-Fi network. We do not include capture because we install with cable and virtual machine. In any case, it is not necessary to be connected to install the system and the Wi-Fi network can be configured later.

3. Keyboard layout

The next step will be to configure the keyboard layout, which should be set automatically according to the chosen language.

Keep in mind:

In our case we choose the Spanish language and the default layout is Spanish, so simply click on Continue. You can check that everything is correct in the field “Type here to test the keyboard”, for example, by entering letters like ñ or ç, typical of Spanish keyboards. Use “Detect keyboard layout” only if you have problems, usually not necessary.

4. Updates and other software

In this section, the type of installation is determined, with various options regarding the packages to be installed.

Keep in mind:

The difference between “Normal installation” and “Minimum installation” is explained in detail at the time and has hardly changed. If you have doubts, choose the normal one. Checking the box “Download updates when installing Ubuntu” is recommended only if it has been a short time since the installation image came out and you have a good Internet connection. Check the box “Install third-party programs … »It is advisable in all cases to improve the user experience (install the drivers for the graphics card, the network card, the video codec, etc.)

5. Installation type

This is the most complex step in the installation, since the configuration varies from installing on an empty disk, installing with another operating system, creating or modifying partitions, etc .; and information can be lost if it is not done well. Once you have configured this section and agree to continue with the installation, the changes will be written to the disk. Until then you can cancel the installation without affecting anything that is already installed on your computer.

For this guide we have differentiated the three situations that we consider to be the most common.

5.1 Basic installation

If you install Ubuntu on a computer with one or more empty disks or with partitions or data that you are not interested in keeping, the option “Erase disk and install Ubuntu” does not fail and will do everything automatically.

If you only have one disk, the installation will start immediately. If you have more than one, in the next step you can choose which Ubuntu is installed.

Keep in mind:

In the drop-down of “Select the drive” you can choose the corresponding disk. When in doubt, Linux sorts connected storage as “sda”, “sdb”, “sdc”, etc. Also look at the size of each disk to know for sure where you are going to install.

5.2 Basic encrypted installation

If you want to encrypt the installation, click on the “Advanced features” box (first image of the basic installation) and check the options “Use LVM in Ubuntu installation” and “Encrypt Ubuntu installation for greater security”.

This is the simplest and most direct method of encrypting the disk, which is usually a good security practice, especially recommended on notebook computers. If you choose to encrypt the disk, in the next step you will have to choose a password.

Keep in mind:

Pay attention to the notice of the installer, because if you lose the password, you will lose access to the system and your data. Since you are already encrypting the disk, checking the box “Overwrite the empty space of the disk” is an option that will only delay the process and that you can skip.

5.3 Ubuntu installation with Windows

This is possibly one of the most common use cases for new users and the Ubuntu installer will detect it without any problem, allowing you to proceed with the installation with a simple additional step.

However, since it is most likely that Windows occupies the entire disk, before proceeding it is essential to make space to avoid losing information. The safest way to do this is to prepare the partitions from Windows, for which we recommend the following guide:

(When the new Windows 10 update comes out, our MC mates will update the guide for Ubuntu 20.04 and we will the link and this note, but the process is the same.)

In short, the options are to free up space and create partitions to install Ubuntu from Windows, or simply free up enough space how to install Ubuntu. For example, if you have a 120GB drive and want to give Ubuntu half, be sure to free up 60GB. But be careful: it is important that each system has as much free space as possible, do not rush because you will have problems.

In our example we have installed Ubuntu on a 50 GB disk completely occupied by Windows 10. By default Ubuntu is allocated 15.6 GB (25% of the total), but it is possible to modify it in a very simple way, since the installer of Ubuntu allows to resize the space available at the moment.

5.5 Advanced installation

Choosing “More options” (first image of the basic installation) you will access the system partitioner, where you can configure everything in detail, including encryption of partitions, mount points, etc.

The example image shows the configuration that we have used for the installation of Ubuntu together with Windows, with two disks and a couple of partitions for each system, but it may vary depending on the disks and partitions that are available and that is why this section deserves an exclusive tutorial that does not fit here. Maybe we will publish it later, but in the meantime there are things that have not changed much from a few years to this part and our old Ubuntu guides can help you get an idea of ​​how to get around here:

However, please note that some of the steps shown in both guides are outdated, so we strongly recommend that If you don’t know what you touch, don’t touch it. The installation methods explained above should suffice for most users. That said, this is the method that most experienced users will choose, because it is the most flexible.

Also note that once the disk is partitioned, the system installation will begin and there will be no going back. Up to this point all changes are reversible.

6. Location

Installation has already started, but a couple of sections still need to be completed. The first, the place where you are, to set the system time.

7. Creation of users

We come to the last step of the installation, the creation of the user. As simple as filling in the information you request.

Keep in mind:

The name of the team is automatically filled in, but you can edit it if you want. If you have performed the encrypted basic installation and the only user of the team is going to be you, you can check the option to “Sign in automatically”, since you must already enter a password in starting the machine.

All you have to do is wait for the installation to complete while watching the presentation slides go by…

The duration of the installation can vary: in older equipment it can take around half an hour, while in new equipment it is reduced to between 5 and 15 minutes. When the time comes the installer will ask to restart, remove the installation image from the computer and press enter to restart the system.
