Can't PXE Boot

I have a Dell Latitude 7350 (2-in-1) laptop.  I have the Dell Docking Station K10A    I am following this link to create a SCCM/CM2012 image.   <ADMIN NOTE: Broken link has been removed from this post by Dell>.

I have gone into the BIOS \ Advanced Boot Options \ ENABLED UEFI.

Then then reboot and press F12.   I get my menu and I've picked both USB NIC (IPV6) and USB NIC (IPV4).  I get another menu (in extremely small font) that says:

press f1/volumeup key to retry boot

press f2/volumndown key to reboot into setup

press f5/home key to run onboard diagnostics

I then went into the BIOS and I disabled "secure boot"  I get the same result.

So how do you PXE Boot using this docking station?
