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”
- At boot, Press the F2 key (or alternately press the F12 key then select the option to enter the BIOS setup).
- 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.
- Create bootable Ubuntu USB (Or any other linux distro)
- Put USB in the right USB Type-C port. Only the right USB port will be detected in the boot options.
- Reboot the system, press F12.
- Select your USB in the boot options.
