According to what you said, you want to create a new partition on your MBR drive that already has four primary partitions. As we know, an MBR drive can only hold at most four primary partitions or three primary partitions plus one extended partition. In this case, you need to first convert one of your primary partitions to a logical partition and then create new partitions.
To meet both of your requirements, I recommend you use EaseUS Partition Master to convert the primary partition to logical with data safe and efficiently create a new partition on the MBR drive. As a professional and reliable partition manager software, EaseUS Partition Master enables you to handle various partition tasks with its easy-to-use tools. Download EaseUS Partition Master and follow the two guides below:
Guide 1. Convert Primary Partition to Logical Partition
Due to the partition limitation of the MBR drive, you should change one primary partition to logical. Here is how to do it with EaseUS Partition Master:
Step 1. Run EaseUS Partition Master and navigate to "Partition Manager."
Step 2. Right-click the primary partition and click "Advanced" to choose "Primary to Logical."
Step 3. Press the "Execute 1 Task" button and click "Apply" to confirm the conversion.
After the conversion, you can refer to guide 2 to create new partitions.
Guide 2. Create a New Partition
If there is unallocated space on the MBR drive, skip to step 3 and finish the process by following the tutorial:
Step 1. Create unallocated space.
Right-click the partition with free space and pick "Resize/Move."
Shrink the partition by dragging the right or left end of the partition. Click "OK" to go on.
Step 2. Enter Partition Manager and right-click the unallocated space to click "Create."
Step 3. Customize the advanced settings, including partition size, drive letter, partition label, and file system. Click "OK."
Step 4. Select "Execute 1 Task" and "Apply" to create a new partition on your MBR drive.
