XPS 13 - Boot from USB

It seems booting Linux through USB (created via Unetbootin) is quite tricky. The following configuration need to be set in your XPS BIOS setting before you can boot Linux from USB.

1. Start your XPS 13 and press F12 to enter BIOS Setup
2. In the BIOS Setup:

• POST Behavior > Fastboot. Change to Thorough option
• Secure Boot > Disable
• Switch SATA Operation to AHCI
• After all the above options/setting have been configured, go to Boot order option to add USB in the list
