Hard Drive and Partitioning Basics
What is a partition?
A partition is a basic container for data on your hard drive. Although most hard drives have only one partition, System Commander 2000 allows you to divide up a hard drive into several distinct partitions. Each partition occupies a physically separate area of the hard drive and functions almost as if it were an independent hard drive. Because of this, a partition can be given its own name, or label, can contain its own operating system and file system, or can simply operate as an additional area for better organization of your files. In Windows and Dos, partition are usually assigned drive letters such as C:, D:, E:, etc.
Types of Partitions -Partition Terminology
Primary partitions
A hard drive can be divided up into a maximum of four primary partitions. The first partition on a hard drive is numbered Partition 0; subsequent primary partitions are Partition 1, 2, and 3.
Extended and Logical Partitions
In order to provide more than four partitions, a primary partition can be designated as an extended partition. An extended partition can be subdivided into several more sections known as logical partitions.
Bootable Partitions
Some partitions can be made bootable, which means that an operating system can be started up from within that partition. A bootable partition is also known as an active partition. A non-bootable partition cannot initialize an operating system. The ability for a partition to be bootable is controlled by the operating system. For example, DOS, Windows 95, and Windows 98 allow only primary partitions to be bootable and will not allow a logical partition to be bootable. By contrast, other operating systems including OS/2 and Linux can be installed to allow a logical partition to bootable. In order to start up, every PC must contain at least one bootable partition. Using Windows 95/98 or DOS, this partition is normally the first active primary partition (Partition 0) of the first hard drive in the computer (Drive 0), and is by default assigned the drive letter C:. To run more than one operating system on your PC ，you will typically want to configure a separate bootable partition for each OS. Partitioning and booting characteristics of several operating systems are discussed more fully in Appendix C: Additional considerations.

硬盘和分区基础
什么是分区？
分区是硬盘上存储数据的基本单位。虽然大多数的硬盘只有一个分区，但是2000系统允许你将一个硬盘分割为几个不同的分区。每个分区占据硬盘上单独的物理区域，并且功能上看上去象一个[屏蔽]的硬盘。正因为如此，分区能够有自己的名字或标签并能够有自己的操作系统和文件系统，或能作为更好组织文件的额外区域。在windows和dos中，分区通常被分配如下驱动器名：C D E等等

分区的种类－－－－分区术语

主分区


一个硬盘能最多分4个主分区，硬盘上的第一个分区被标记为0分区。接下来的分区依次被标为1，2，3分区


扩展分区和逻辑分区

为了提供超过4个的分区服务，一个主分区能被设置为一个扩展分区，一个扩展分区能再分为几个我们称之为逻辑分区的部分。
可启动分区


一些分区能够被设置为可启动，那 意味着一个操作系统可以从这个分区启动，启动分区也叫做活动分区。一个非启动分区不能初始化一个操作系统。使一个分区启动由炒作系统控制。例如DOS, Windows 95, and Windows 98 只允许一个主分区可启动，并且不允许逻辑分区可启动。为了启动，每个pc都要至少有一个启动分区。95/98 or DOS的使用中，这个分区通常是计算机的第一个硬盘的第一个分区，而且被默认的分配c盘标记，为了运行更多的操作系统，你将要为每个操作系统分配[屏蔽]的可启动分区。
有关多个操作系统的分区和启动特性将在附录c中详细讨论：额外考虑的细节。
