Clover to OC failure

Hi all, running Success' href='/2020/12/install-macos-catalina-on-supported-pc.html'>Catalina on Clover for several years, all is working great!
Now tried to remove Clover and switch to OpenCore. Done all configuration's per OpenCore Coffee lake guide on EFI, now cannot boot...
When boot, receive:
OpenCore Boot Menu (REL-078...)
> 1. Reset NVRAM
[Restart][Shutdown]

and that's it...

What have i done wrong?

I have my old EFI backed up, ill try to restore to it.
