  2. 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 ...

  3. BIOS parameter block - Wikipedia

    en.wikipedia.org/wiki/BIOS_parameter_block

    In computing, the BIOS parameter block, often shortened to BPB, is a data structure in the volume boot record (VBR) describing the physical layout of a data storage volume. On partitioned devices, such as hard disks, the BPB describes the volume partition, whereas, on unpartitioned devices, such as floppy disks, it describes the entire medium ...

  4. Comparison of bootloaders - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_bootloaders

    Note: The column MBR (Master Boot Record) refers to whether or not the boot loader can be stored in the first sector of a mass storage device. The column VBR (Volume Boot Record) refers to the ability of the boot loader to be stored in the first sector of any partition on a mass storage device.

  5. Windows Boot Manager - Wikipedia

    en.wikipedia.org/wiki/Windows_Boot_Manager

    On system with BIOS firmware, the BIOS invokes MBR boot code from a hard disk drive at startup. The MBR boot code and the VBR boot code are OS-specific. In Microsoft Windows, the MBR boot code tries to find an active partition (the MBR is only 512 bytes), then executes the VBR boot code of an active partition.

  6. Master boot record - Wikipedia

    en.wikipedia.org/wiki/Master_boot_record

    These boot sectors expect the FDISK partition table scheme to be in use and scans the list of partitions in the MBR's embedded partition table to find the only one that is marked with the active flag. [24] It then loads and runs the volume boot record (VBR) of the active partition.

  7. Partition type - Wikipedia

    en.wikipedia.org/wiki/Partition_type

    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 ...
