Hi
I have the exact same problem when trying to boot.
I got the EFI folder from Intel Coffee Lake but my disk looks a little different.
My folders on the USB are as shown. EFI, FILES, INSTALL MACOS CATALINA.APP, DONATE-BEER, OLARILLA.COM, README, RESTORE IMAGE, TUTORIAL.
This is after flashing using Belena Etcher.
Please help quick, this is urgent
