instal Mac on internal ssd hard

I wanted to install Windows on my MacBook (MacBook Pro 13 Retina in early 2015). Unfortunately, it was not successful, and I lost my Mac system. Now, when I want to install Yosemite (command+r), my system can't find the SSD hard. How can I solve my problem? In addition, when I open my system and connect the SSD to another system, it can read it. What should I do to solve my problem?
