The master boot record is located in the first sector of a hard drive, and while it has different functions it is commonly known for finding bootable partitions in the partition tables and loading the boot sector which often is a boot loader.

A damaged or modified MBR can have the result that the operating systems cannot be loaded which is what the Alureon Rootkit caused on some operating systems.
