  2. Master boot record - Wikipedia

    en.wikipedia.org/wiki/Master_boot_record

    The MBR bootstrap code loads and runs (a boot loader- or operating system-dependent) volume boot record code that is located at the beginning of the "active" partition. The volume boot record will fit within a 512-byte sector, but it is safe for the MBR code to load additional sectors to accommodate boot loaders longer than one sector, provided ...

  3. Volume boot record - Wikipedia

    en.wikipedia.org/wiki/Volume_boot_record

    On partitioned devices, it is the first sector of an individual partition on the device, with the first sector of the entire device being a Master Boot Record (MBR) containing the partition table. The code in volume boot records is invoked either directly by the machine's firmware or indirectly by code in the master boot record or a boot ...

  4. GUID Partition Table - Wikipedia

    en.wikipedia.org/wiki/GUID_Partition_Table

    The Master Boot Record (MBR) partitioning scheme, widely used since the early 1980s, imposed limitations for use of modern hardware. The available size for block addresses and related information is limited to 32 bits.

  5. 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 ...

  6. Extended boot record - Wikipedia

    en.wikipedia.org/wiki/Extended_boot_record

    An extended boot record (EBR), [1] or extended partition boot record (EPBR), [note 1] is a descriptor for a logical partition under the common DOS disk drive partitioning system. In that system, when one (and only one) partition record entry in the master boot record (MBR) is designated an extended partition , then that partition can be ...

  7. NTFS - Wikipedia

    en.wikipedia.org/wiki/NTFS

    The size of a partition in the Master Boot Record (MBR) is limited to 2 TiB with a hard drive with 512-byte physical sectors, [24] [25] although for a 4 KiB physical sector the MBR partition size limit is 16 TiB.

  9. Track0 - Wikipedia

    en.wikipedia.org/wiki/Track0

    The first sector of Track0 is known as the master boot record (MBR) and contains the initial code used to boot the operating system (bootstrap code). Near the end of the MBR is the Partition Table: a predefined structure containing the layout of the disk.
