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, where “n” is the number of the partition that you do not want. However, when you try to delete hidden or protected partition like OEM partition that is 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 or you might receive “Can’t delete a protected partition without force protected parameter set” error in Diskpart window. In such 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.
