Unable to Create Partitions Because the Disk Already Contains the Maximum Numbers of Partitions

When I try to create a new partition on my MBR drive with four primary partitions, I get the error message: You cannot create a new volume in this unallocated space because the disk already contains the maximum number of partitions. How can I fix it? Or is there any way to create partitions without caring about the error?

You cannot create a 5th primary partition because an MBR has a limited maximum primary partition of 4. However, you can have three primary partitions and one extended partition. The extended partition doesn't store data but can hold many logical partitions. Hence, you can fix unable to create partitions problem by changing one of the existing primary partitions into an extended partition.
