Need “delete partition override” command

It is well known that unwanted partition can be easily removed using Disk Management or Diskaprt “delete partition n” command (“n” is the number of the partition that you will delete). However, when you try to delete hidden or protected partition like OEM partition offered by computer manufacturers and used to reset your PC to factory settings, you will find that the option of “Delete Volume” is grayed out in Disk Management.

If you turn to DiskPart, you might receive “Can’t delete a protected partition without force protected parameter set” error. In such a case, you need to add “override” parameter to delete the protected partition. The step-by-step tutorial is listed as follows (Take removing OEM partition as an example):

1. Run Diskpart as administrator: press “Windows + R” keys at the same time to open Run Dialogue. Then type “diskpart” and hit “Enter”.

2. Type the commands given below and hit “Enter” key after every command:

  • list disk - to present all disks on your computer

  • select disk f – “f” is the number of the disk that contains the OEM partition

  • list partition – to display all partitions on the disk

  • select partition q – "q" is the number of the OEM partition going to be deleted

  • delete partition override

Within a few seconds, Diskpart will successfully delete the protected OEM partition. Then, type “exit”.

The “delete partition override” command is still not supported on system partition, boot partition or the partition that contains page file, hibernation file or crash dump file.
Don’t hurry up to delete OEM partition before you backup it to another hard drive or confirm that you don’t need to reset your PC to factory settings anymore.
