1. 🧩The partitioning process takes some time, so please do not perform other tasks in the middle and let your computer complete the partitioning first.
2. 🔎If there are 4 primary partitions on the MBR disk, the split partitions will be automatically converted into logical partitions.
3. ⚒️If there are four primary partitions on the hard drive, Windows does not allow you to split the system partition or the boot partition unless you can convert one of the other partitions from primary to logical partition first.

In addition to split partition in Windows 10/11/8/7, EaseUS Partition Master also comes with many other amazing features to help Windows users resize hard drive partition without losing data, such as:

• Create or delete partitions
• Move the partition to the end of the disk

• Merge two adjacent partitions into one partition (opposite of splitting a partition)
• Allocate free space from one partition to another partition

Method 2. Use Disk Management

Step 1. Right click the Windows icon and select "Disk Management" to open it.

Step 2. Then, right-click on the large partition you want to shrink and select "Shrink Volume."

Step 3. Disk Management then calculates how much space can be reduced. In the next window, enter the size (in MB) you want to shrink and click "Shrink" to continue.

Step 4. Then you will see the unallocated space after the shrunken partition. Now right click on it and select "New Simple Volume" and follow the New Simple Volume wizard to create a new partition on the unallocated space.

In this way, your large partition is divided into two partitions. Disk Management needs to shrink this large volume first. If you are not familiar with computer operations, it is recommended that you use EaseUS Partition Master to avoid data loss.
