Are you sure you installed the right recovery for your device or that you didn't accidentally wipe your device first things first if you do have your back up go into recovery and wipe both caches then full wipe/factory reset then try to reinstall your back up then wipe both caches again and try to boot up and see what happens if it boots sweet if not then you should download a custom ROM to your computer transfer it and gapps to your phone and install that using same steps, wipe caches, full wipe/ factory reset,install ROM,install gapps, wipe caches again and then reboot hope this helps...
