I was creating a new Micro SD card with the purpose of using an NFS Root for the Raspberry Pi.
Can a Raspberry Pi boot from a MBT partition?
And since ESPs can exist on either GPT or MBR partitioned disks, and the Pis already support MBR/ 0x0c and MBR/ 0x0e as partition types to load the boot files from then, provided that this is not dictated only by the SoC mask ROM, the only requirement to achieve that is adding MBR/ 0xef as another supported partition type.
Where are the boot files stored on a Raspberry Pi?
In a basic Raspberry Pi OS install, the boot files are stored on the first partition of the SD card, which is formatted with the FAT file system. This means that it can be read on Windows, macOS, and Linux devices.
