how to hard reset Lenovo Yogo S1 Windows 8

[dathagreen]

I recently bought a Lenovo Yogo S1 Windows 8 laptop from a local garage sale. When I follow the general directions to advance to log in screen "press ctrl/alt/delete" It provides to me the login screen and it asks for "user name" followed by "password". The strange thing that I'm having a hard time trying to bypass is that directly under those two bars it says, "Sign in to: SAINTLEO . Then below those words are two different links that say, "How do I sing in to another domain?" and "Sign-in options".
Mind you I am not a student of SaintLeo nor do I know whose laptop that originally was, basically all I want and need to know is how can i hard reset this computer to simple original Lenovo Yoga S1 Windows 8 settings!
