Clover to OC failure

Hi all, running Catalina on Clover for several years, all is working great!
Now tried to remove Clover and switch to OC. Done all configuration's per OC 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.
