What are the various protocols in use for booting from GPT partitions

So far, the only supported protocol is to have the bootable partition(s) present inth the MBR. Data-only partitions can be present in the GPT only.

Sorry, but isn't it so, that BIOS loads and executes the boot sector (MBR) and
does not care about any partitions ?

This is correct. However, the handover protocol from the MBR to the operating system boot sector uses a (possibly synthetic) structure in MBR partition table format. Furthermore, not all operating systems can boot off any partition table format even though they may be able to use it for data.
