Which type of disk encryption protects the MBR (master boot record) file of the system?

Disk encryption is a technology which protects information by converting it into unreadable code that cannot be deciphered easily by unauthorized people. Disk encryption uses disk encryption software or hardware to encrypt every bit of data that goes on a disk or disk volume. Disk encryption prevents unauthorized access to data storage.
Expressions full disk encryption (FDE) or whole disk encryption often signify that everything on disk is encrypted – including the programs that can encrypt bootable operating system partitions – when part of the disk is necessarily not encrypted. On systems that use a master boot record (MBR), that part of the disk remains non encrypted. Some hardware-based full disk encryption systems can truly encrypt an entire boot disk, including the MBR.
