Q: MacBook won't recognize new SSD

ddecided to upgrade my hd to a ssd. created a bootable usb with El Capitan. When I boot into recovery mode my MacBook doesn't recognize the usb or the new SSD. I then decided to just fresh install El Capitan on old hd and clone it to an internal hard drive I have for storage. I tried to put the hd back in and I keep getting an error has occurned message when I boot up. I then booted in recovery mode to delete the hd and install el capital via the Internet. Keeps saying that the installation of El capitan has failed and to try again. This has happened 2 times. I'm out of ideas on what to do. Help!!!!
