- boot sector
- Part of a hard disc, floppy disc, or similar data storage device that contains code for bootstrapping programs (usually, but not necessarily, operating systems) stored in other parts of the disc.
- data storage device
- See physical device.
- disk geometry
- Set of disk attributes that specify format, partitioning etc. of a disk
- drive letter
- Abstraction at the user level to distinguish one disk or partition from another. For example, the path C:\WINDOWS\represents a directory WINDOWS on the partition represented by C:.
- FAT (File Allocation Table)
- File that contains the records of every other file and directory in a FAT-formatted hard disk drive. The operating system needs this information to access the files. There are FAT32, FAT16 and FAT versions.

- physical device geometry
- see Disk Geometry
- MBR (Master Boot Record)
- All disks start with a boot sector. When you start the computer, the code in the MBR executes before the operating system is started. The location of the MBR is always track (cylinder) 0, side (head) 0, and sector 1. The MBR contains a file system identifier.
- MFT or MFT records (Master File Table)
- File that contains the records of every other file and directory in an NTFS-formatted hard disk drive. The operating system needs this information to access the files.
- system partition
- Name commonly used for the partition that contains the operating system files.
- Virtual RAID Virtual Disk Array
- Software layer that sits above assembled physical disks that were part of a hardware RAID system.
- volume boot record

It contains code to load and invoke the operating system (or other standalone program) installed on that device or within that partition.
