Ubuntu 22.04 LTS is now out and has massive improvements over Ubuntu 20.04 LTS. I have remade this video using newer Dell hardware such as an XPS 13 9305 and XPS 13 9365:

Ubuntu is the Linux distribution with most support from hardware vendors. Dell in particular test a large proportion of their hardware with Linux Ubuntu. In this video I go through a Clean Install on Ubuntu 20.04 on an OptiPlex 7040 using a UEFI BIOS and Secure Boot. For a complete install including codecs and third party drivers, we need to set up a Machine Owner Key (MOK) to allow it to pass Secure Boot. I then move over to a 2 in 1 Latitude 7350. This system also had native complete driver support and the touchscreen and auto-rotation worked out of the box. I change some of the settings to optimise the system for tablet use.

Make sure your UEFI BIOS is up to date before attempting the installation. For instructions on updating the UEFI BIOS using the UEFI BIOS Boot Menu and a USB Flash Drive see:

Note Dell have responded to GRUB2 Bootloader CVE-2020-10713 by issuing newer UEFI BIOS Updates. These UEFI BIOS Updates address the Security exploit but will block older installers which used the GRUB2 Bootloader such as Ubuntu 20.04. Make sure you are installing from Ubuntu 2004.1 (patch 1) installation media or later which has an updated GRUB2 Bootloader.

Also make sure your SATA Operation is AHCI as Ubuntu does not support a RAID SATA Operation.

If you get stuck on a black screen with Dell and Ubuntu logo with white spinner after installing updates use the Ubuntu Recovery options:
