Disk Partition in Windows 10: [Practical Guide With Images]

Whether you make the disk partition or not, doesn’t matter. But you need to know how to make the disk partition on Windows 10. And this is exactly what you get from this page step-by-step.

As PC users, we need to know some basic computer knowledge. And this information of partitioning a hard disk or other storage in Windows PC is a part of that.

We commonly use two methods to make disk partitions on a PC. One is using the free Windows 10 home application “Disk Management.” And the other is using third-party software like EaseUS, etc.

If you want free third-party software to make disk partitions on your PC, you can find that at the end of this page.

I recommend you should avoid using third-party software for disk management because of the following disadvantages:

  • It consumes local disk C space – if you have less storage, it will cause lag in your PC
  • It consumes RAM – if your PC has less RAM like 4 GB, the memory management error will occur
  • On a laptop computer, the more apps you use, the more battery it consumes

However, you can use third-party software for disk partition if you think your PC is good enough to avoid the listed disadvantages.

Simple methods to get into disk management of Windows 10:

To make a partition of a disk, we need to get into the disk management page. There are some simple ways to get into the disk management page.

Disk Partition in Windows 10 (step-by-step) :

A disk partition is not a one-click process and also it is not a difficult process as well. However, the below steps will get you through the process.

1. Select the disk that you want to make a change

In the first step, you need to select the disk that you want to shrink the volume. My recommendation is to select the high-volume device to shrink because it gives a balanced disk partition.

In the above picture, you can see that two storage devices are present in my system. One is Kingston SSD storage with the name Disk 1. And the other is a Seagate 1 TB hard disk named Disk 2.

Because Windows is running on ‘Disk C’ and I have enough volume on ‘Disk C’ (not more and not less). So, I don’t want to make changes to it. The hard disk is my option for partitioning.

2. Select the option ‘Shrink Volume’

For example, if I want to take storage from ‘Local Disk G’, right-click on it. The options will be displayed like this.

The shrinking volume of a disk

From them, select ‘Shrink volume‘. A new tab will open.

3. Enter the volume that you want in MBs

It looks like the pic below. Here you can enter the volume (in MBs) that you want.

Select Volume to shrink

If you are trying to make a mismatching partition, then the message will be displayed like this “You can not shrink a volume beyond a point where any unmovable files are located.”

After you select the volume that you want to shrink, click on Shrink.

4. Windows will keep the shrank volume as unallocated memory

There is no need to change the disk partition on my PC. So, I’m not doing it. But I’m just showing you how to make it.

After you shrink the volume from a disk, Windows will keep this shrunk volume as “Unallocated Memory.”

From the pic, you can see the Unallocated Memory of 51 MB in Disk 1. Usually, it is shown in Black color.

5. Create a new volume space

To use this Unallocated memory, right-click on it. The options will display like this.

Creating New Simple Volume

Select “New Simple Volume” from it.

Simple Volume Wizard of Windows 10

Volume Wizard will open. Click on “Next.”

The wizard will ask the volume size (in MBs) that you want to make the Volume capacity of a Disk.

Volume assigning to new Disk

After you select the volume, click on “Next.”

Give a drive letter to the New Disk. It is required for identification. If you don’t want to, click on “Do not assign a drive letter or drive path.” And tap on “Next.”

Assigning the Drive letter to the New Disk

That’s it. Your new Disk is ready to use. You can “Merge” the Unallocated Memory to another disk.

Through this process, you can make a new disk partition on a Windows 10 PC. Hope this information will help you to make this disk partition process by yourself.

I think now you can find the disk volumes and access them easily. However, if you feel this task is difficult, here is the best free disk partition software you should go through.
