Hi, I had a similar issue with a hackintosh before where clover would not see the installed partition but the apfs drivers solved that issue.
You usually install Clover to the bootloader, but you can also install it to a small pendrive and boot from it, I have one in a 128mb usb drive, it boots all my intel hackintoshes but of course it hangs when I try to use it in my machine with Ryzen. So I wanted to create another clover usb boot drive just for AMD Ryzen CPUs. Having a backup drive to use to boot into osx can save your life when playing with kexts. I also have managed to boot from the USB clover boot drive, then used a vanilla created installer inside a Mac and it would work just fine as well.
not sure where the edit button is, one more thing I wanted to add, After following the latest guide and replacing all the files mentioned there I see that clovers boots in textonly instead of showing you the theme gui, tried using a different theme other than the embedded one and still get a text only screen. That's the only difference I notice when booting from the clover created by default and the one I have after replacing all the files mentioned in the guide here:
Ok, I just had success booting my install, the install was always complete but Clover would not see it. I recreated the USB installer according to the guide but instead of deleting all the drivers inside DriversUEFI64, I left them and only copied aptiomemoryfix.efi and hpfsplus.efi, left apfsdriverloader.efi instead of deleting it and putting AppleImageLoader.efi instead. Clover still looks crappy but now it sees all the partitions and is able to boot into them
