A "startup disk" is a volume or partition of a drive that contains a usable operating system. You can set your Mac to automatically use a specific startup volume, or you can temporarily override this choice at startup.
If you do not have usable operating system on your SSD, it won't appear on the Startup Manager window.

Do I need to do this?
Yes, if you want to have your SSD visible on the Startup Manager screen.
How to do it. Use Recovery Partition to install OS X on SSD drive. OS X Yosemite: Reinstall OS X

Feb 14, 2015 9:37 AMby drivemaster,Thank you all very much. I downloaded OS and dropped it on the new SSD and installed it on the SSD and everything is working fine I am booting to the new SSD. Next I will try to remove the OS off of the spinning drive. But I will need some help for this to happen. Is this a good idea or just leave it alone?
