Citar:Several major kinds of boot sectors could be encountered on IBM PC compatible hard disks, floppy disks and similar storage devices:
A master boot record (MBR) is the first sector of a data storage device that has been partitioned. The MBR sector may contain code to locate the active partition and invoke its Volume Boot Record.
A volume boot record (VBR) is the first sector of a data storage device that has not been partitioned, or the first sector of an individual partition on a data storage device that has been partitioned. It may contain code to load and invoke an operating system (or other standalone program) installed on that device or within that partition.
To be a valid boot sector, the two-byte hexadecimal sequence 0x55, 0xAA (called the boot sector signature) must exist at the end of the sector; otherwise, either the BIOS or MBR code will report an error message and halt any OS bootstrapping process.
CD-ROMs usually have their own structure of boot sectors, for IBM PC compatible systems this is subject to El Torito specifications.
Non IBM PC compatible systems may have different boot sector formats on their disk devices.
