Cant PXE boot Dell 5290 2-in-1

We recently acquired a Dell 5290 2-in-1 and had some issues PXE booting the device using the Dell USB C dock. Altering the following BIOS settings enabled the PXE boot option

  • Boot device and enter BIOS by pressing F2 at startup
  • Navigate to POST Behaviour -> FastBoot and select Thorough
  • Navigate to System Configuration -> USB/Thunderbolt Configurations
  • Enable Thunderbolt Boot Support
  • Navigate to General -> Advanced Boot Options
  • Enable UEFI Network Stack
  • Apply the settings and reboot the laptop
  • Press F12 to enter boot options and PXE Boot should now be available
