Windows 10 hdd has locked

[Sgtjacques]

My windows 10 hdd has locked itself and now i cant unlock it. I came back to my pc and it was locked up so i hit the reset button. I then got a black screen telling me to insert a boot drive. Further looking into it, it turns out that my hdd locked itself. Can anyone help?
