5 An EFI partition can reside on a disk with an MBR (legacy)
6 partitioning scheme, GPT scheme, El Torito CD-ROM boot entry, etc. For
7 MBR, 0xEF partition ID is used, and the same platform ID is used in El
8 Torito; GPT uses a corresponding GUID.

13 No, the UEFI specification mandates that FAT12/16/32 EFI partitions
14 must be supported, but allows the firmware to support other
15 filesystems, with or without the 0xEF / GUID marker above.
