Some users may encounter the following problem:

There are four primary partitions in the hard disk. However, the fifth partition cannot be created. Because of MBR hard disk limitations, either up to four primary partitions or up to three primary partitions plus an extended partition can be created for each basic MBR hard disk. If you want to create more than four partitions, you need to convert one primary partition to logical partition first.

With the help of partition manager software - EaseUS Partition Master, you can easily convert primary partition to logical partition without data loss.
