2. Boot disk - Wikipedia

   en.wikipedia.org/wiki/Boot_disk

   A boot disk is a removable digital data storage medium from which a computer can load and run an operating system or utility program. [1] The computer must have a built-in program which will load and execute a program from a boot disk meeting certain standards.

3. System partition and boot partition - Wikipedia

   en.wikipedia.org/wiki/System_partition_and_boot...

   The boot partition is a primary partition that contains the boot loader, a piece of software responsible for booting the operating system. For example, in the standard Linux directory layout ( Filesystem Hierarchy Standard ), boot files (such as the kernel , initrd , and boot loader GRUB ) are mounted at /boot/ . [ 1 ]

4. Boot sector - Wikipedia

   en.wikipedia.org/wiki/Boot_sector

   A boot sector is the sector of a persistent data storage device (e.g., hard disk, floppy disk, optical disc, etc.) which contains machine code to be loaded into random-access memory (RAM) and then executed by a computer system's built-in firmware (e.g., the BIOS).

5. EFI system partition - Wikipedia

   en.wikipedia.org/wiki/EFI_System_partition

   UEFI firmware supports booting from removable storage devices such as USB flash drives. For that purpose, a removable device is formatted with a FAT12, FAT16 or FAT32 file system, while a boot loader needs to be stored according to the standard ESP file hierarchy, or by providing a complete path of a boot loader to the system's boot manager. On ...

6. Design of the FAT file system - Wikipedia

   en.wikipedia.org/wiki/Design_of_the_FAT_file_system

   On non-partitioned storage devices, such as floppy disks, the Boot Sector is the first sector (logical sector 0 with physical CHS address 0/0/1 or LBA address 0). For partitioned storage devices such as hard disks, the Boot Sector is the first sector of a partition, as specified in the partition table of the device.

7. Volume boot record - Wikipedia

   en.wikipedia.org/wiki/Volume_boot_record

   The boot code in the VBR can assume that the BIOS has set up its data structures and interrupts and initialized the hardware. The code should not assume more than 32 KB of memory to be present for fail-safe operation; [1] if it needs more memory it should query INT 12h for it, since other pre-boot code (such as f.e. BIOS extension overlays, encryption systems, or remote bootstrap loaders) may ...
