You cannot and do not make the swap chain point to other render targets.

The _only_ way to render to the screen is to make a render target for the backbuffer. You first grab the back buffer of the swap chain and then create a render target view using that back buffer.

See http://www.directxtutorial.com/Lesson.aspx?lessonid=111-4-4 for some example code on the process of creating a render target view for the back buffer of a swap chain.

If for some reason you must create a render target view for a different texture (e.g. post processing) you must eventually copy that to a render target view on the back buffer to display it. This is frequently done by rendering a full-screen primitive with a shader that reads from the intermediary buffer and writes to the back buffer's render target view.
