Boot back into Rescuezilla and see if you can see the original drive under GParted Partition Editor, and confirm your source/destination disks are as you intend.
With both Rescuezilla and GParted closed you can open the file manager and confirm your disk contents.
Disconnect the destination disk if possible, because it may interfere with booting.
Did you change your BIOS boot settings in order to boot Rescuezilla? If so, please change it back.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I did clone a drive to have it as a backup. And then did exit the soft and restarted the laptop and I got Boot device not found.
Did I just lose all or what!
