Check your book and make sure you are putting the thread through all the guides before going to the bobbin. My Bernina has a little arrow on the top of my machine to tell me which direction to wind the thread around the little silver disc right before it goes to the bobbin. My bobbin does not look like that when I wind it. Make sure the bobbin is pushed all the way into the spindle before winding also.
Check that your spool is in the right position depending on how the thread is wound on it. Stacked thread spools like to be vertical and cross wound thread spools like to be horizontal.
Opps, just noticed in your picture that your cross wound thread is horizontal so that's not the problem.
