Instead of using the third party tool, go for the Disk Management Software as it is perfectly capable of completing the partitioning process.

Now, check the steps to partition hard drive without formatting Windows 10

Step 1: Go to the Windows search box and type Disk Management in the search bar. An option will appear “Create and format hard disk partition”. Click on that option. A new window will appear like this.


Hit the “Win + R” keys and type “diskmgmt.msc” and enter “OK”



Press “Win + X” buttons and select “Disk Management” from the drop-down list.


Step 2: Now, choose the hard drive from the available list in which you want to create the partition.
If your drive exists one loaded with files and folders, still you need to create some “unallocated space”. Otherwise, no partition will be created before you. Right click on the desired drive and select the “shrink volume” option from the drop-down.

Step 3: Now, the internal structure of the PC will calculate the free space which can be allocated to the new partition. After calculating, it will ask you how much free space you want to use for your new drive. If you want to use all space, just click on the “Shrink button” otherwise specify the size and input it into megabytes before hitting Shrink.

Depending on your disk size, the amount of time taken can vary. After its completion, there will be new “unallocated” space which can be seen in the corresponding physical drive in Disk Management screen.

Step 4: If you are using a new hard disk, just skip this space. Otherwise, right-click the “unallocated” space and choose New Simple Volume

Step 5: Go to the on-screen manual instructions and choose the size of the volume to be used and the drive letter. (By default it will use all unallocated space)

Step 6: It is advised to format new and old drives when creating a new division. If you are given that option, go for that. For “File System”, go for NTFS type

“exFAT” is mainly used for portable devices like Pen Drive.

Step 7: Now, one after another window will appear. Ruthlessly click on the “Next” button and finally hit “Finish” to create the partition. Now, the hard drive will have a very new partition with its own name. In the Disk Management Page, check all your information about it.
