Updating standard boot order ipl rhel
The MBR holds the information on how the logical partitions, containing file systems, are organized on that medium.
The MBR also contains executable code to function as a loader for the installed operating system—usually by passing control over to the loader's second stage, or in conjunction with each partition's volume boot record (VBR).
This MBR code is usually referred to as a boot loader.

MBRs are not present on non-partitioned media such as floppies, superfloppies or other storage devices configured to behave as such.
Support for partitioned media, and thereby the master boot record (MBR), was introduced with IBM PC DOS 2.0 operating system in March 1983 in order to support the 10 MB hard disk of the then-new IBM Personal Computer XT, still using the FAT12 file system.
