Can you create a Mac startup disk with SSD?

Hello, I just purchased and Extreme Portable SSD. It mounts and works fine transferring/storing files. However, when I try to use it to create a start up disk it doesn’t recognize the drive so it won’t let me create one. I’ve seen some things on-line that mentions modifying the code on the mac. Is there a way to create a startup disk WITHOUT modifying the code? I just want to create a startup disk. It should be simple and I missing something?
