Hi i'm a new user of virtual box. I need to test some software on POS ready 7, there is a way i can add this operating system to the list ?

Quick answer: no.

Longer answer: I can't see the point of it. A position in the list implies specific support for that variation, and no such specific support exists. How does "POS ready Win7" differ from ordinary Win7?

As far as I know, it is just Windows 7 optimised for POS. The installation looks identical to the standard Win 7 install and the documentation states it will install on any machine which meets the Win 7 requirements. It should install in the standard Window 7 vm.
