UV Unwrap doesn't work in render view I've been learning how to use Blender, and I've come across a tutorial which talks about UV Unwrapping, but it isn't the same version of Blender that mine is so I have no idea what to do now. My version is 2.79

When you use Blender Internal (as your case), the "Texture" viewport mode shows the texture currently opened during UV Unwrap operations, even with no material assigned to the cube. To show the same texture in rendering you must create a material for the mesh and assign the texture to it, as shown in picture.
