How To Delete Partition In Windows 10 During Installation

 How To Delete Partition In Windows 10 During Installation | You can delete almost any partition (except for the part that makes up your Windows 10 installation), and in this guide, you’ll learn to use three tools to complete this task.

In Windows 10, a partition (or volume) is a logical division of available space on a physical storage drive with a defined file system and settings that the system presents to the user as a separate drive.

Since a drive can contain many partitions, and sometimes, you may need to organize them, Windows 10 includes multiple tools to make it easier to remove those you no longer need to free up more space to increase the size of another partition. Or you can also use the tools provided to clean up your storage to set it up with a different partitioning and file system.

In this Windows 10 guide, we will walk you through the steps for deleting a partition on an internal or external drive using Disk Management, PowerShell, and Command Prompt.

How to delete a partition using Disk Management
To delete a partition (or volume) using Disk Management, use the following steps:

1. Open the Start menu.

3. Select the drive containing the partition you want to remove.
4. Right click (only) on the partition you want to remove and select Delete Volume option.

   In the command, make sure to replace “PARTITION-LETTER” with the letter of the partition you want to delete.

   For example, this command deletes the E partition:

Type Y and hit Enter to confirm the deletion.
After completing the steps, the partition will be removed and the space on the drive will appear as unallocated.
