It shouldn't be this difficult!!!

I just purchased the 3650 with the hopes of cloning existing hard drive and replacing with a SSD.  Accomplished cloning, took out old hard drive, installed new SSD...won't boot!  Have changed settings in boot options as described in several posts to no avail.  NO BOOTABLE DISC FOUND.  Put the old hard drive back in and it boots perfectly.  Followed instructions for cloning to a T.  Help!
