Can't Delete Partition on Windows 10/11? – Here’s How To Fix

This post details how to fix the "cannot delete partition" issue in Windows 11/10.

Part 1. Why Can't I Delete a Partition on Windows 10/11?

Deleting hard drive partitions is necessary, particularly if you are running low on disk space. In such cases, users usually delete the volume that isn't being used to make room for the volume that is nearly full. The Disk Management utility is typically used to delete hard drive partitions. However, there are some cases where the 'Delete volume' option is greyed out, wherein users cannot delete partitions in Windows 10/11.

The following are some of the situations wherein the Delete Volume option is disabled, and you cannot delete the partition:

Removing the OEM/Windows recovery partition

The recovery partition can take up several GB, so it's okay to delete it to free up disk space. However, because the recovery partition is hidden and protected, you cannot delete it in Disk Management.

Deleting the partition from your USB flash drive or SD card

If your operating system is NOT Windows 10 version 1803 or later, you cannot remove the partition from the USB flash drive, or the SD card will be considered a removable device.

Eliminating the system boot partition

Unfortunately, when you want to delete the system C drive in Windows 10/11 Disk Management, the "Delete Volume" option is greyed out. This is because the C drive contains OS boot files for booting and cannot be removed from within Windows.

Because the error isn't the result of various factors, it can fix this problem with two simple solutions listed below.
