What caused this error?

This error message is likely to appear on GPT disk. If the recovery partition you intend to delete is regarded as protected partition by Windows, then deletion is prevented.

Although Diskpart is able to delete recovery partition, without a clear interface to display the details, there are chances that you may delete a wrong partition. For those who are unfamiliar with Diskpart, obviously this is not the best choice.
