Set Partition as Primary

As we all know, there are three kinds of partition on an MBR disk: primary partition, extended partition, and logical partition. Generally speaking, a basic MBR disk supports at most four primary partitions, or up to three primary partitions plus one extended partition. The extended partition cannot be used directly until it is divided into logical partitions. Primary partitions can be converted to logical partition and vice versa. Well, why do users need to set partition as primary and how to convert logical partition to primary partition?

Why Set Partition as Primary

In the beginning, let’s talk about the reason why users need to set partition as primary. In some cases, users want to install another operating system for some purposes. However, we all know that operating systems should be installed on primary partitions. Hence, if the rest partitions are all logical partitions on the drive, they need to convert a logical partition to primary partition. This is because the system files and boot files of each operating system must be saved in their respective primary partitions. Only in this way can these operating systems work normally.

  • At most four primary partitions are allowed on one hard drive.
  • If there are logical partitions on the hard drive, at most three primary partitions are allowed unless users delete the whole extended partition.
  • If there are several logical partitions in an extended partition, users can only set the first one or the last one as primary. Otherwise, there will be two extended partitions if the partition in the middle is converted, which is not accepted by Windows.

    Right-click on the target logical partition which needs changing, and then activate “Set Partition as Primary” from the “Change Partition” group menu.
