Clone copy Sequoia from drive to drive with OCLP

Hi patchers

I installed Sequoia on an external drive with OCLP just for testing. Now that I know for sure that everything runs smoothly I want to clone copy the external disk onto my internal drive.

I followed the steps advised in some YT videos, I copied the whole drive onto the internal one with CCC and then, with MountEFI I copied the EFI folders, but when I boot it I get three options with the terminal icon, BootKicker, OpenShell.efi and Reset NVRAM.

What am I doing wrong?

I must admit that those tutorials were for Sonoma but I don't think it is much different.. is it?

Thank you
