During the registration of your images you are asked if you wish to create a software package
This package is used to deploy the image to the Scalbility server.
Simply deploy the package to your scalability server via software delivery and the image will be added to your boot server.
There is no need to stage the package into the scalability servers software library and in fact this would just be a waste of space.
The boot server stores its image in a totally different location to software delivery.
