It turns out that this was a problem with the Trusted Platform Module. Apparently it didn’t like the new O/S being installed on hardware it had already “signed”. Not being too schooled in how TPM works, I’m making an assumption here, but clearing the TPM after deployment fixed my bootup problem. This can be done in the BIOS, or by letting the system boot from the Hard Drive at the Fog Menu, then running tpm.msc and clearing it there.
