Insulating an unheated attic with a floor

I have very liitle loos insulation under the planks in my attic, if i were to lay rolls of insultation over existing floor would this work, or would i need to pull the floor up and lay insulation underneath the floor boards.

According to other threads, many have had stunning success by rolling out the fiberglass over the floor, paperside down.

I intend to blow insulation underneath the boards so I can use the space. However, i'm still researching how to properly do that, since all how-to-blow-insulation photos show some professional blowing it over open joists. They make it look childishly easy. Blowing into a confined space without having pockets or compression is something else!
