Can't make a partition (greyed out) of my new SSD - OS X El Capitan

Hi guys, i'd appreciate some advice.

I have a mid 2012 Macbook Air. Just bought a new OWC 240GB SSD to upgrade my hardware. I've been through all the process for reinstaling my backup from a Time Machine. But when i get to the Disk Utility i cannot make a partition. Also, it only shows a 2GB SSD instead of a 240GB SSD.
