The issue you describe sounds like a P.O.S.T. failure. When you first start a computer whether it's a smartphone or a super computer and everything in between runs a Power On Self Test. This is the first program that every computer runs before the operating system is loaded. If there is a failure the computer will not boot. The P.O.S.T. is controlled by the BIOS. Chance are your BIOS cant' see the drive. The easy way to resolve this issue is to boot into your BIOS set-up utility and change your boot order manually. Chances are with a hard drive change the BIOS can't find the operating system. Also you may need to update your BIOS to the latest version. An updated BIOS may include the driver necessary for the BIOS to read or see your new drive. I had the exact same problem with my Lenovo Y700-17ISK. This model has 2 internal hard drives. When I removed the rotational hard drive and installed a Crucial SSD and reinstalled the OS the computer would not boot. Once I manually change the boot order the computer started normally. Also to boot from a M2.NVME hard drive you must have a dedicated boot partition. I currently run Xubuntu 16.04 64-bit LTS so the procedure was simple. Since you are using a Intel processor your Mac is really a PC. Do yourself a big favor, update your BIOS, install Linux ; there are 300 different versions and you are sure to find something that will suit your needs. This is a very secure, sophisticated OS that will run on any hardware. And the best thing is it's free!
