render problem (part)

I tried to render out an image but it renders only a part of it not the whole picture in the camera when I tried to fix it everything turned pink. So now I am totaly lost. I hit F12 as I am supposed so, but it only renderd a part of the picture. I have checked every settings for rendering and have tried box selecting from camera view(I had been told if you select from camera view it will render only the parts selected, but I checked it cannot be the issue) but it didn’t work. If you need I can attech the blend file. Can any one help?

Pink usually indicates that a texture is missing.
