Rob - see below, you might want to subscribe to the bug too. Suggestion is to use firmware .iso and a more verbose dd line to ensure you've actually written the whole image correctly.
Also, I would suggest enabling TPM and secure boot unless you are *absolutely* sure that you don't need them. Secure boot is well supported in Debian.
