You don't clarify whether you are referring to the built-in keyboard of the MacBook Pro or an external keyboard. In either case, one that fails across two different operating systems has issues. If it is an internal keyboard, schedule time with an Apple Store, or Apple Authorized Service Center. EIther keyboard may need replacement.
