Disk Sectors
You need to be aware of disk sectors to use the installation tool. We'll discuss sectors in more detail in Chapter 18, but for now you just need to be aware that a sector is a tiny section of a disk. Each sector has a number. Sector 0 is at the beginning of the disk, and the sectors are numbered sequentially until the end of the disk.Partitions can be defined by the sectors that they occupy. On most disks, the Master Boot Record takes up the first 62 sectors. The next partition would start at sector 63 and go on for a size you indicate.
