In this article, you will learn how to Ubuntu 20.04 LTS with screenshots. If you prefer an upgrade, read our guide that shows How To Upgrade to Ubuntu 20.04 from Ubuntu 18.04 & 19.10.

Installation of Ubuntu 20.04 LTS Desktop

1. Once you have obtained the Ubuntu 20.04 desktop image, create a bootable media using Rufus tool or create a bootable USB drive using LiveUSB Creator called Unetbootin.

2. Next, insert the bootable DVD or USB into the appropriate drive on your machine. Then start the computer and instruct the BIOS by pressing a special function key (F2, F8, F9 or F10, F11, F12) to boot-up from the inserted USB/CD drive.

Once the BIOS detects the bootable media, it boots from it. After a successful boot, the installer will check your disk (file system), press Ctrl+C to skip this process.

3. When disk checking is complete or if you have canceled it, after a few seconds, you should see the Ubuntu 20.04 welcome page as shown in the following screenshot.

Select Install Ubuntu.

4. Next, choose your keyboard layout and click Continue.

5. After that, choose the apps you want to install based on the installation type (normal or minimal installation). Also, check the option to install updates during the installation process and where to install third-party software.

Choose Ubuntu Installation Type

6. Now choose the actual installation type. This is normally the most confusing part, especially for new Linux users. There are two scenarios we will consider here.

First is using an unpartitioned hard drive with no operating system installed. Then secondly, we will also consider how to install on an already partitioned hard drive (with an existing OS e.g Ubuntu 18.04).

Scenario 1: Using an Unpartitioned Harddrive (without an OS installed)

7. For this scenario, you need to set up partitions manually so choose Something else and click Continue.

Choose Ubuntu Installation Type
Choose Ubuntu Installation Type

8. Now you need to partition your hard drive for the installation. Simply select/click on the unpartitioned storage device from the list of available storage devices. Then click New Partition Table.

Note that the installer will auto-select the device on which the boot-loader will be installed as shown in the following screenshot.

Create New Partition Table

9. Next, click Continue from the pop-up window to create an empty partition table on the device.

10. Now you should be able to see the free space created equivalent to the capacity of the hard drive. Double click on the free space to create a partition as described next.

11. To create a root(/) partition (where the base system files will be installed), enter the size of the new partition out of the total free space. Then set the file system type to EXT4 and the mount point to / from the drop-down list.

Create Root Partition

12. Now the new partition should appear in the list of partition as shown in the next screenshot.

  1. So, things seemed to be on par with what I did, with the exception being that I booted from a USB in the UEFI shell menu of a Chromebook. I have yet to see any install window open up. I have a picture of a cat, the date/time, speaker volume icon, and battery icon at the top of the screen. Can anyone tell me wtf happened?

    Long story, my roommate asked me to make her Chromebook better, and 2 weeks later, I have removed chrome, attempted to install windows, (the SDD was too small to accommodate this), then said screw it and attempted to recover the Chromebook back to normal with the previously flashed image of ChromeOS I put together.

    Ya, no. Didn’t work. At all. 3 days solid of trying everything I could think of, and useless google searches lead me to learn I could possibly reinstall ChromeOS using ubuntu. 4 days spent on that, and finally, I gave up and typed exit into the UEFI shell from the boot menu, and then hark, there it is, ubuntu apparently installing on the computer.

    Now I have worse than a brick with an uninstallable windows os, I have a desktop with a picture of a line cat, date/time, volume, and battery icons, and nothing more. Is there additional software I need to load onto another USB drive to make this work, or do I spend this week’s pay and swallow my pride? Any help is much appreciated.

  2. Please take a backup of data as the disk is formated whole assigning space for the root directory. If Windows is installed, then use the Windows tool or other software to create a new partition of the disk from the free space of some partition. Then use the new partition for installing ubuntu.

    Thanks

  4. Doesn’t work, says missing EFI, doesn’t auto-detect swap, and I can’t format either of them to be what they need to be.

    • Yep same for me – would be nice to know exactly what partitions are required and the minimum sizes so we can alter your instructions to our particular situation.

  5. It isn’t clear to me that these instructions do what I want to do. I have 19.10 and I want to upgrade to 20.04 LTS. I also want to make a few changes as possible.

    By way of contrast, https://linuxconfig.org/how-to-upgrade-ubuntu-to-20-04-lts-focal-fossa#h4-how-to-upgrade-ubuntu-the-debian-way is not only quite clear about what it does and how it does it but also it does not require making a boot medium.
