if you don't have an old mac that you can make a bootable usb with then you can download the macos for whatever version you want and continue with olarila guide if you are now running windows, just make a bootable usb with 16 GB usb or above after downloading the mac os then replace the efi with mine
https://www.olarila.com/topic/20908-guide-easy-fast-and-perfect-hackintosh-vanilla-step-by-step-clover-and-opencore-bootloader-windows-linux-or-macos/
follow up with the guide only the first and second step, after that look how the guide put the efi folder, then put my efi instead, , then you are good to go, keep me updated, good luck

I have now the Problem, that my nvme isn’t on the disk Utility *lol* edit: okay, found a way: in Bios edit to ahci modus thanks for your help

[haunetal1990]

Next problem: there's no a install icon on the boot menu.
Folder com.apple.recovery.boot is on the usb with the recovery from monterey.

I have only in the menu "reset NVRAM" and the "toogle SIP"

log: 00:000 00:000 OCS: No schema for LoadEarly at 3 index, context !

did you install the mac os correctly on the usb ?
can you tell me how you did it exactly

[haunetal1990]

what do you mean with "install the mac os correctly on the usb"?
i used the opencore install manual. So my usb has the fat32 format, the efi folder from you and the two macrevovery files from the macrecovery.py in the com.apple.recovery.boot folder.
Or did u use a other way?

have you installed mac os alredy ?
you have to install and make a bootable mac os on the usb and put my efi in the efi partitioan
give a read here

I updated the repo to fix No schema for LoadEarly, check it now

[haunetal1990]

have you installed mac os alredy ? you have to install and make a bootable mac os on the usb and put my efi in the efi partitioan give a read here https://dortania.github.io/OpenCore-Install-Guide/installer-guide/

the OpenCore Install Guide is the manual, that i used, but i build first a usb with efi and the revovery from apple (like the installer guide https://dortania.github.io/OpenCore-Install-Guide/installer-guide/winblows-install.html#downloading-macos ). And the Boot menu from OpenCore don't show that extra menu.
Did u have a manual for how to make a bootable mac os on the usb?

Edit: in the config file, you musst Disable HideAuxiliary and than you can see the MacOs Recovery Install file.
And for log file: the value "target" set to 67

After that, the apple logo was only visible and i can't install MacOs,

Which Bios Settings did u use? Secure Boot is false and other things?
