I'm having the same error. Can you clarify in exaclty what steps you made to fix the error and during what part of the process?

@Ralph45 I think @SteveWUK had to create a GUID APFS volume on the new SSD before using Disk Utility to restore the drive. I would suggest you use Carbon Copy Cloner (CCC) instead of Disk Utility as CCC will also recreate the hidden Recovery Partition for you. I've had trouble using Disk Utility to create bootable clones sometimes so now I always use CCC.
Another good option is to do a clean install of macOS on the new SSD, then use Migration Assistant on the first boot to transfer your User Folder(s), data, settings and even apps to the new SSD. With this option, you will need to reapply any proprietary license keys for MS Office, etc. as they don't seem to transfer. If OSX 10.12.4 or newer has already been installed on this system, then you should be able to boot into Internet Recovery Mode to install the OS without needing a boot disk.
