Thanks for a great job. I frequently read your guides and they always help me and so far I never need to reply but today I found a problem at the end which I can not solve so far.
I just did all the steps described here and than when I tried to boot my Surface Pro 3 from PXE I got a Bios message "Invalid signature detected. Check secure boot policy in setup" seconds after PXE IPv4 message shows up.
I'm using Surface Pro 3 (I just installed the latest HW upgrades offered but this was happening before the FW upgrade too).
I'm using a Surface Pro 3 docking station with Ethernet port and I also tried to boot with and USB adapter (100 mbit Model 1552).
I always get this bios message and than that its over with PXE boot.
My PXE boot was Ok on all other computers so far but I was only deploying Windows 7 so far. I must admit I know very little about UEFI at this point in time and so far we survived without it (or at least without noticing it).
Do you have an Idea what to try next?
Do I need the Gigabit USB adapter?
My PXE is configured via DHCP.
I have SCCM v 5.00.7958.1000 CU1 installed.
