No, a belief has to be justified and true to be a justified true belief. One can believe something that is neither justified or true, but even this requires a justified true belief from which to start. Justified true belief is knowledge, hence all belief must start with a justified true belief. Even beliefs that are not true or justified must rely on a justified true belief. You cannot get to anything except experience, but that experience cannot even be ordered without knowledge.
By ordered I mean accommodated and assimilated, processed and analyzed. None of your experiences can be organized without a system by which to organize them any organizational system will at least require the a priori knowledge that A=A.
