How to create a Primary Partition

Basic disk storage supports partition-oriented disks. A basic disk is a physical disk that contains primary partitions, extended partitions or logical drives. A maximum of four partitions can be created on any hard disk. The limitation of four is one that is imposed on the system by the way that the master boot record is structured. Only one partition can be made as active and active partition will be used for booting the computer. The four partitions can be all primary partitions, three primary partitions with an extended partition. The extended partition may then be subdivided into multiple logical partitions.

Almost all disk management functions can be performed using Disk Management MMC snap-in. Disk Management MMC snap-in is available as an extension to the Computer Management MMC snap-in. To open the Computer Management MMC snap-in, right click My Computer and select "Manage" from the context menu. Expand Storage node and select "Disk Management".
