Boot cloned HDD

[Henning]

Hi. I copied my Clover based Yosemite HDD with CCC.
Next I installed Clover Bootloader an copied my EFI Folder from the EFI-Partition of the original to the EFI Folder at the clone.
When I try to start after a few seconds I got the prohibited Sign.
What's wrong?

Did you select to make the clone copy bootable?

Yes.
