Windows 11 or 10: How to Delete, Create and format Partitions

Learn the steps to delete, create or format partitions on Windows 11 or 10 for installed Hard disk or SSD drives to claim and utilize their full storage capacity.

Imagine your existing PC has a conventional hard drive, however, now you want to add one more drive or SSD.  And of course, the latter one will be used to boot the OS whereas the previous one will act as pure Data storage. After successfully migrating the OS and other data from your Hard drive, you would want to delete all the extra partitions on the old boot drive to use its total capacity. For this task, we recommend Disk Management, which you can find by searching the Windows taskbar.

Here in this tutorial, we will learn how to use Disk Management to delete, create and format partitions on Windows 11 or 10.

 2. Find the Drive

Now it’s time to determine the right drive. In the upper area, in the Volume column, you can see the respective labels and drive letters. Our example is the HDD (D:) volume. In addition to the name, you may also be able to refer to the capacity that is also listed.

3. Select and Delete Volume

When you select the volume, the corresponding area appears hatched at the bottom of the window. In addition, in our case, there are two or more partitions on the disk. To get rid of them, right-click on it, select Delete Volume from the context menu and answer the question with Yes.

In this way first, delete all the available volumes or partitions on this disk to free all the available disk space.

4. Delete Volume Greyed Out in Disk Management

However, what happens if you don’t get the “Delete Volume” option to remove the Disk partition on Windows 11 or 10? For example, you can see that in below-given screenshot we are not getting the “Delete Volume” option for Disk 3’s First partition. In such a case, we will use the command prompt to delete the volumes.

Open Command prompt, terminal, or Powershell

Right-Click on the Windows 11 Start button and select Terminal (Admin); on Windows 10 you may have Powershell (Admin). Confirm the default query of the User Account Control by clicking on the Yes button.

Here we are selecting our disk, assigned number 3.

List all the available partitions:

Now, let’s list all the available partitions under the selected DISK.


Once you have identified which Partition you want to delete, select that using its serial number. For example:

DELETE Windows 11 partition using the command terminal

Once you have selected the partition, you can delete it using the given command.


Based on our above example, the commands will select disk 3 and select partition 1. Then delete the selected partition with the command delete partition or in case of an error message occurs then use the  delete partition override command:

Disk Management

You can now close the command prompt and return to Disk Management. There you have the possibility to allocate the freed-up space elsewhere, for example by enlarging another partition.

Again Delete the rest of the partition you are seeing on your Disk Management Interface.

Assign Volume Size

If you are planning to create multiple partitions on Windows 10 or 11 then enter the amount of space you want to assign to your partition. Whereas those who want to use complete space of the Hard disk without multiple partitions instead want a big partition that uses the whole space of the drive, leave the default volume size as it is and simply click on the NEXT button.

What are Create and Format hard disk partitions mean in Windows?

Create and Format Hard disk partitions” is another term used for Disk Management in Windows 11 or 10. This feature is used to manage attached hard disks; for formatting, creating, and deleting partitions of a hard drive. Also, we can put any drive offline or online using this feature of Windows.

What does it mean to format partition?

Format partition means, selecting any partition of the attached hard drive in Windows, macOS, or Linux and deleting or erasing the data of the selected partition while assigning a particular type of file system such as NTFS, ext4, FAT, and more…

What is the difference between format and partition?

Partition Disk stands for Split Disk. By default, you get hard drives of new PCs or laptops in one piece. You can logically partition them so that you have several “smaller hard disks” virtually (depending on how much you partition) on them. It means you are specifying the boundaries of areas (storage space) on the disk. On the other hand, Formatting is creating a filesystem volume. For example, you have a free space on a drive just like a white piece of paper where you are creating a table for storing filesystem volume objects like files and directories.

Does formatting a disk erase everything?

Yes, formatting will erase all data available on your Disk. However, the data can be recovered, if, after formatting, nothing has been stored on it again. For recovery, we need a special kind of software such as stellar data recovery.

What happens if I format my hard drive?

When we hit the Format button for any Hard drive, the system will erase all the data and pointers allocated for them to make space for new data. In short, all of your data will be gone, once you format your hard drive.
