[23] On Windows XP 64-Bit Edition and later, access to the EFI system partition is obtained by running the mountvol command. Mounts the EFI system partition on the specified drive.
Boot Configuration Data is stored in a data file that has the same format as Windows Registry hives and is eventually mounted at registry key HKEY_LOCAL_MACHINE\BCD00000 [6] (with restricted permissions [7]). For UEFI boot, the file is located at /EFI/Microsoft/Boot/BCD on the EFI System Partition.
The EFI System partition holds a filesystem and files used by the UEFI, while the BIOS boot partition is used in BIOS-based systems and accessed without a filesystem by holding raw binary code. The size requirements for a BIOS boot partition are quite low so it can be as small as about 30 KiB; however, as future boot loaders might require more ...
Since Windows NT 3.1 (the first version of Windows NT), [4] Microsoft has defined the terms as follows: The system partition (or system volume) [5] is a primary partition that contains the boot loader, a piece of software responsible for booting the operating system.

The GUID Partition Table (Globally Unique IDentifier) is a part of the Unified Extensible Firmware Interface (UEFI) standard for the layout of the partition table on a physical hard disk. Many operating systems now support this standard. However, Windows does not support this on BIOS based computers. [10]
At the end of the hardware initialization, the boot ROM will try to load a bootloader from external peripheral(s) (such as a hard disk drive or solid-state drive, an eMMC or eUFS card, a microSD card, an external EEPROM, and so on) or through specific protocol(s) on a communications port (such as a serial port or Ethernet, etc.).
The partition type (or partition ID) in a partition's entry in the partition table inside a master boot record (MBR) is a byte value intended to specify the file system the partition contains or to flag special access methods used to access these partitions (e.g. special CHS mappings, LBA access, logical mapped geometries, special driver access, hidden partitions, secured or encrypted file ...
