Convert primary to logical

A basic MBR disk can have either up to four primary partitions, or up to three primary partitions plus an 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 that currently has four primary partitions.

To convert a primary partition to logical:
1. Right-click the primary partition that you want to convert and then click Convert to logical.
2. The operation will be pended until executed in Pending Operation List. Click Execute Operation when you are ready to proceed.

◆ Converting the boot partition or the system partition to logical partition is not available. Otherwise, the computer may have a bootable issue.
◆ The size of the converted partition might be slightly different from that of the original primary partition, as some space might be required to store supplementary information.
