No option to boot into Catalina from OpenCore

Hi,

I'm new to Hackintosh so this is probably an easy one. I'm following the guide here to create an OpenCore bootloader on a usb hard drive. I'm using an EFI I downloaded here created by someone for my machine. gibMacOs sucessfully partitioned the drive and flashed everything, I then copied the downloaded EFI stuff into the efi folder on the drive. From here my laptop will boot into OpenCore but just shows a single option 'reset nvram' in the upper left corner:

Sorry it blurry, it resets quickly! It says: OpenCore Boot Menu, 1. Reset NVRAM, Choose boot entry!

What am I doing wrong?

Thanks :)
