I just recently bought my house and the previous people were renters and did not winterize NO COVER! It is frozen solid or at least it seems so. I have never had a pool so I am new to all of this and that is why it did not seem like a concern which I am WRONG. I bought a cover for it is there something I can do to save my pool?

Cover or no cover they all freeze in the winter if you have below 32 degree. The water will be dirtier this spring than if it had a cover but its all cleanable.
