(computing) A dedicated block usually at the beginning (first block on first track) of a storage medium that holds special data used to start a system. Some systems use a boot block of several physical sectors, while some use only one boot sector. Other manufacturers use the terms boot block and boot sector interchangeably.
This example show various components of GNU GRUB distributed over sectors of a hard disk. When GRUB is installed on a hard disk, boot.img is written into the boot sector of that hard disk. boot.img has a size of only 446 bytes.
