No bootable devices.

I'm on a dell latitude E6520 with an i7-2620M trying to install MacOS Success' href='/2020/12/install-macos-catalina-on-supported-pc.html'>Catalina. I've tried a lot of guides but whatever i do i always get: "No bootable devices--strike F1 to retry boot, F2 for setup utility".

I've tried these guides: osxlatitude (without a "bootpack"), r/Hackintosh vanilla guide, r/Hackintosh laptop guide? and one other i can't remember.

I've also tried creating my own config.plist to no avail.

I'm lost here and i was hoping someone here could help me.
