✍ Note: If you want to delete a system partition, you need to first insert a USB drive into your computer and use the AOMEI software to create a bootable USB. Then, restart your computer and enter the BIOS settings to boot from the USB. Finally, click and run AOMEI and choose Delete Partition.

Step 2. In the small pop-up window, choose “Delete partition quickly (delete partition without wiping data)” and click on OK.

Step 3. Return to the software's main screen, press "Apply," then click "Proceed" to initiate the deletion process.

Method 2. Enable the Virtual Disk Service

Sometimes, the Virtual Disk Service error: the operation is not supported by the object occurs because you disabled the related service. You can go to the Virtual Disk Properties to check and enable it.

Step 1. Press the Win + R keys to open the Run utility. Then type services.msc in the text box and press Enter.

Step 2. In the Services window, scroll down to find Virtual Disk. Double-click the service to enter its Properties window.

Step 3. Set the Startup type to Automatic. Then click the Start button if the Service status shows Stopped.

Step 4. After that, click Apply > OK to save the changes. Once done, restart your computer to see if the “the operation is not supported by the object delete partition” issue has been solved.

Method 3. Run Diskpart delete the partition override command

Running delete partition override command can remove hidden or protected partition. You can follow the steps to use Diskpart to fix the operation is not supported by the object issue.

Notice:

The "delete partition override" command is invalid for deleting system partitions, boot partitions, or partitions that store important files like the page file, hibernation file, or crash dump file.

Before deleting an OEM partition, kindly please ensure you've backed it up to another hard drive or verified that you no longer require it for resetting your PC to factory settings.

First, press “Win+ R”, input “diskpart” and click “OK” to open the command-line utility. Then, run the following command:

▪ diskpart
▪ list disk: all the hard drives on your computer will be displayed.
▪ select disk n: n stands for the disk number of disk that contains the to-be-deleted partition
▪ list partition: all the partitions on the selected disk will be listed
▪ select partition n: n is the number of the partition you want to delete
▪ delete partition (override)

However, this method does not always work. You may still encounter 'Diskpart: the operation is not supported by the object' after using a command like this:

This error may be because you perform a Diskpart deletion on a dynamic disk. To solve it, you can use AOMEI Partition Assistant to convert the dynamic disk to a basic disk without losing data, and then delete the hidden or protected partition, such as removing OEM partition again.
