[Solved] Boot from USB on Dell XPS 13 9370

Ubuntu works very well on XPS laptops, but it is not so easy getting the laptop to boot from a USB.

Step 1: Change POST Behavior from “Fastboot” to “Thorough”

  1. At boot, Press the F2 key (or alternately press the F12 key then select the option to enter the BIOS setup).
  2. In POST Behavior, Select – Fastboot the select the Thorough option.

Step 2: Put USB in the right USB Type-C port

This is the main trick I have been unable to find documented anywhere else. The BIOS only recognizes bootable media in the right USB port.

  1. Create bootable Ubuntu USB (Or any other linux distro)
  2. Put USB in the right USB Type-C port. Only the right USB port will be detected in the boot options.
  3. Reboot the system, press F12.
  4. Select your USB in the boot options.
