Well, what is primary partition and logical drive? Or what’s their exact difference? Here are answers.
Tip: since logical drive is related to extended partition, then we will explain features of primary partition, extended partition, and logical drive.
Primary Partition is the hard disk partition where both Windows OS and other data can be stored, and it is the only partition that can be set active. can be set active for BIOS to locate, and the primary partition saving boot files must be set active. If not, Windows will be unbootable. In addition, at a time only one primary partition on one hard disk can be set active. On an MBR disk, there can only be 4 primary partitions or 3 primary partitions plus 1 extended partition at most.
Here Are 3 Solutions after Accidentally Marking Drive C Active
Windows won’t boot after accidentally marking drive C active? This post tells which partition should be set active and gives 3 solutions to fix this issue.
Properly speaking, Extended Partition is just a defined area where logical drives reside. We have said MBR disks can hold 4 primary partitions at most. In order to create more than 4 partitions, extended partition is introduced. On the area belonging to extended partition, we can create lots of logical drives. Nevertheless, one hard disk can hold the maximum number of 1 extended partition.
Logical Drive is the hard disk partition created in extended partition. Like primary partition, a logical partition can be used to install Windows and any other types of files, but we are unable to set it active.

Tip: In Disk Management, unpartitioned space in primary partition area is called unallocated space, while unpartitioned space in extended partition area is named free space; unallocated can’t be used to extend to or create logical partition, and free space can’t be used to enlarge to or create primary partition. But MiniTool Partition Wizard can break this limit. If you do not believe me, download the free edition of the program to have a try.

Why and How to Convert Logical Partition to Primary
