Go: http://www.jb51.net/diannaojichu/55058.html active partition is the computer boot partition, the operating system's boot files are installed in this partition, Windows system is generally default to C drive, and Linux is based on the specific settings
When you start the system, the operating system on the active partition executes a process called a drive image that assigns a drive name to the primary partition and logical drive. All primary partitions are first imaged, while logical drives are specified with subsequent letters.
hard disk active partition definition
In a hard disk, there can be only one active partition.
Method of marking a disk partition as active or canceling activity
The system partition must be a primary partition that has been marked as active for startup and must be on a disk that is accessed by the computer when the system is started. The same disk can have only one active system partition at a time. You can have more than one basic disk, one active partition per disk. However, you can only start the computer from a specified disk. If you need to use a different operating system, you must first mark its system partition as active before restarting the computer.
You cannot mark an existing dynamic volume as active. However, you can convert the basic disk containing the active partition into a dynamic disk. After the disk is converted, the partition becomes the active simple volume. If the active partition is not the current system partition or boot partition, it becomes a simple volume and loses its record in the partition table, so that it is no longer active.
In fact, the active partition is written in the main section of the boot data, it can complete with the BIOS handover start task, such as a series of actions, to guide the system.
The main partition is best only one, otherwise the management will be more troublesome, at present, the small point of the hard disk 10G can, big can consider 15--20g about, too big there is no meaning

2. Use the "LIST Disk" command to determine the # #号 of your mobile hard drive;
3. Use "Select Disk 0" to set your mobile disk as the current operating disk;
4: Use the "LIST PARTITION" command to determine the # #号 of your hard drive partition;
5. Use "Select PARTITION 1" To set the first partition as the current operation partition;
6. Use the "INACTIVE" command to unlock the active state of the current partition.
