Just got a brand spanking new Z440 and I'm creating an image for it to be deployed via PXE boot using a Microsoft WDS server. Out of the pox, I can choose F12 at startup and it displays my 2 nics. Choosing either one just takes me to the BIOS setup screen. If i disable secure boot and go with Legacy boot, I can F12 and it will start the usual PXE boot sequence, contacting my DHCP server.
I'd really like to take advantage of UEFI but I've never got it to work correctly on any of the HP notebooks, tablets or workstations. Is there a trick to all this?
