Clients do not properly boot to a PXE Menu whether through a Reboot to Automation task or by manually booting client.

PXE boot options menu only contains option to boot to 'Next Device (BIOS/EFI)'

NBS General settings were not configured to respond to computer under either of the scenarios(unknown, predefined, or managed).

Configuring NBS settings for SBS to respond to clients with a specific preboot configuration allowed clients to boot with the PXE boot menu as expected.  

See Configuring and Filtering Computers to Boot with PXE

Further note:  PXE M0F is not an error and reflects a successful PXE boot encounter as far as the nic's boot agent is concerned.
