I am attempting to install Sierra on a new 480Gb PNY SSD drive to replace my 120Gb Samsung SSD which has gotten full. I am currently running Yosemite and decided to get a new drive and do a fresh install of Mac OS X with Unibeast. After creating the boot drive USB with Unibeast, and booting from it, I am able to get to the Mac OS install page and install Sierra on my desired drive, however, when I reboot and get to the Clover Screen from the USB, I am not able to see my new PNY Sierra...
