SCCM PXE Boot Issues - UEFI and Secure Boot

Image
Issue:
When attempting to image a machine using SCCM with UEFI and Secure boot on, you will get an error that states

Windows failed to start. A recent hardware or software change might be the cause.
File: \Boot\BCD
Status: 0xc000000f
Info: An error occurred while attempting to read the boot configuration data.


Resolution:

Disable Secure Boot and computer will image as intended

SCCM PXE Boot Issues - No Advertisements Found

Image
I've been battling with a pervasive issue with SCCM where the computer fails to install the SCCM task sequence on the first try, it won't ever boot again. It will constantly just present you with a "failed to boot" message, or something of that regard. Then when you attempt to boot it again, in the SMSPXE.log, it will give you an error that says "no advertisements found". You can see a sample of that log below


This is by design of the SCCM system. It won't attempt to rerun a required deployment to the same MAC address.

Resolution:
I had only set up a deployment to unknown computers as required. The workaround I came up with is to also deploy an "Available" deployment to unknown computers. This will cause the task sequence to be offered as an optional deployment, and give you the chance to re-run the task sequence.
