Does Secure Boot only work with GPT?

Secure boot is only relevant to verifying the boot software. It works with both MBR and GPT devices. The constraints are actually that of the firmware: UEFI needs GPT (except in Legacy mode), while BIOS needs MBR. As a GPT disk has a fake MBR header, it can work with a device that requires MBR (with limitations).
