Hello,

Your first sector contains several partitions and this is why the loader
ignores partition table. From one side MBR has the PMBR partition, that
needed for GPT, but PMBR isn't correct in your case.
Actually your configuration is similar to what called Bootcamp, but it
isn't correct bootcamp :)
I modified the code to be less strict for you case. Can you try this loader?
