Unless you made a system disc and copied your OS to another drive or media, you can't roll back to 8 from 8.1.

***Edit for clarity.
If you have 8 installed on a hidden drive then you would have to set that as active and do a completely fresh install. You would lose any data that is currently on your drive so back up any important data before proceeding.
