That is standard for GPT and the PMBR. Do not use MBR utilities on GPT
disks. The PMBR is there so a GPT disk will boot on a BIOS system, and
modifying it with MBR utilities probably won't help but can definitely
hurt.
There are several reasons a UEFI system might not boot. Make sure you
have the latest UEFI firmware for the motherboard. Turn off Secure
Boot. For BIOS-based systems, several notable manufacturers like
IBM/Lenovo and HP have mis-used certain partition types for their own
purposes, breaking GPT compatibility.
For hopelessly broken UEFI or BIOS systems, using the old MBR format is
necessary.
