NOTE: Dell Docks that use Display-Link drivers (for example, the D6000 series and D3100) will not allow PXE boot. Drivers for these docks do not load in a pre-Windows environment. While Dell does not recommend you PXE boot through a dock connection, you can accomplish this using a USB Type-C to Ethernet dongle (such as Dell SKU# 470-ABND) to complete PXE boot.

Enable PXE boot in BIOS for Latitude 7x20 and 7x30

  1. Select Connection, then ensure that Enable UEFI Network Stack is set to Enabled.
