How to Make More Than 4 Partitions on MBR Disk

Updated on Dec 11, 2018 by Daisy to Partition Master

In this article, you can learn to create a MBR disk or convert a GPT disk to MBR disk, and then make more than 4 partitions/volumes on MBR disk in Windows 10/8.1/8/7/Vista/XP.

How Can I Create 4 More Partitions on Windows 10 Computer:

"Hi, I tried to use EaseUS Partition Master to create the fifth partition on my Windows 10 computer, but I failed. It told me to convert an existed primary partition to logical partition and try again. I don't understand. Is it because MBR disk does not allow more than four partitions on it? Should I convert MBR disk to GPT disk to fix the problem? I need your help."

The Master Boot Record (MBR) contains only four entries/slots for four PRIMARY partitions, or three PRIMARY partitions and one EXTENDED partition. So, if you want to make more than four partitions on an MBR disk in Windows 10, to make it possible, you have to change at least one primary partition to an extended partition as EaseUS Partition Master suggests.

How to Make More Than 4 Partitions on MBR Disk in Windows 10

EaseUS free partition manager allows users to create more than four partitions on an MBR disk. Note that an extended partition must contain unallocated space within it so you can create an unlimited number of logical partitions. In general, there are three different ways to create additional logical partitions.

Situation 1: Disk does not have any partitions

Use "Create partition" to create 3 Primary partitions, then create the last one with Extended type. More Logical partitions can be created within Extended.

If you want to create a partition on an empty USB, SD card or external hard drive, connect it to your PC in advance.

Step 1: Launch EaseUS Partition Master

On the main window, right-click on the unallocated space on your hard drive or external storage device and select "Create".

Create partition on unallocated space

Step 2: Adjust the new partition size, file system, label, etc.

Set the size, partition label, drive letter, file system, etc. for the new partition and click "OK" to continue.

Set up new partition

Step 3: Confirm to create a new partition

Click on the "Execute Operation" button and confirm to create a new partition by clicking "Apply".

Confirm and keep all changes

Situation 2: The disk has three primary partitions without unallocated space available

Use "Resize/Move partitions" to shrink one of the partitions (the last one is preferable) and create Unallocated space, then use "Create partition" to create an Extended type partition. More Logical partitions can be created within Extended.

Situation 3: Disk already has four primary partitions

Either delete one Primary partition or convert Primary to Logical. Then use "Move/Resize partitions" to shrink this Logical partition to free Unallocated space for creating other Logical partition within Extended.
