How to Convert Primary Partition to Logical Drive?
Why you need to convert primary partition to logical?
Primary partition: A partition type which can be created on basic disk. It is a part of physical disk and works like a physically dependent disk. As for MBR (Main Boot Record) disk, 4 primary partitions or 3 primary partitions and 1 extended partition which contains more than one logical partitions can be created. For GPT (Globally Unique Identifier Partition Table) disk, up to 128 primary partitions can be created.
Logical partition: It is also a partition type which is different from primary partition. Each primary partition has its own boot block while logical partition has not; each primary partition can be set as start area using fdisk while logical partition cannot.
Primary partition also called primary disk partition. In a primary partition, any other partition type cannot exist. Therefore, every primary can be viewed as a logical disk. On this point, primary partition is very similar to logical partition. However, primary is divided directly from hard disk while logical partition must be created on extended partition. The files and data needed to start a computer are included in the primary partition on its hard disk. On the other hand, if you want to install OS (Operating System) on a certain hard disk, it must have at least one primary partition on it. As for logical partition, they are used for saving data.
If one MBR disk has four primary partitions, you will not be allowed to create other new partitions on that disk. Because a basic MBR disk can have either up to four primary volumes, or up to three primary partitions plus one extended partition which contains unlimited number of logical partitions. You need to convert a primary partition to logical if you want to create a fifth partition on a disk which already has four primary partitions. AOMEI Partition Assistant supports converting between logical partition and primary partition.
Before you do
If there are other applications running on the partition which you are going to perform, AOMEI Partition Assistant will notice you to close those applications or to execute this operation in PreOS Mode.
It would be advisable to make reliable backup for your valuable data to the external media such as networks, CD/DVD or external hard disk drive, the professional backup software – AOMEI Backupper may help you out. It is always better to be cautions than sorry.

Note:
Convert primary partition to logical is mainly used on basic MBR disk.
You’re not allowed to convert a boot partition to logical. Otherwise, you computer will likely to stop working.
The location and the size of the primary partition will be slightly changed after converting. Since the logical partition is 63 sectors bigger than primary partition.
Besides converting primary partition to logical one, you can also convert logical drive to primary partition. The operations for converting logical partition to primary are quiet similar to those of converting primary drive to logical.
