Primary partition and logical partition are two partition types. Why should we convert a primary partition to logical partition? Before answering this question, we would like to begin with what’s the difference between primary partition and logical partition.
Primary partition: A primary partition can be used to install system, but only one primary partition can be set as active at one time. The boot files and data are stored in the primary partition. For MBR disk, there are 4 primary partitions or 3 primary partitions plus 1 extended partition. A extended partition can be further divided into more logical partitions. For GPT disk, up to 128 primary partitions can be created under Windows.
Logical partition: Logical partition is similar with primary partition, except that you cannot install system on it. Logical partitions are usually used to save data.
Their differences: A primary is divided directly from hard disk while logical partition must be created on extended partition. Each primary partition has its own boot block while logical partition does not contain; each primary partition can be set as start area by using “fdisk” while logical partition cannot.
Why convert: If you want to create a fifth partition on a disk which already has four primary partitions, you need to convert a primary partition to logical. MiniTool Partition Wizard helps the conversion between logical partition and primary partition.
