I like to "do" or I don't like to "do" - you can express by nominalizing verb into noun form, so in Korean it would sound like "I like running", 윤희씨 below showed how to make noun form from a verb - Vst+기 or Vst+는 것.. As for Vst+러 "하다" it's used to do something in order to do other thing, like "I went to a grocery store to buy some milk".. and verb 좋아하다 is a transitive verb that requires an object (noun or noun form) and to point that some noun is an object you use 을/를.. Thus, Vst+기를 좋아해요 or Vst+는 것을 싫어요.. 저는 달리기를 싫어요ㅎㅎ
