Mounting Mac EFI messes up the Windows boot

[Carlos Vico]

Hello everyone,

First, excuse me if I say something obviously wrong or stupid because I am starting watching videos, reading and trying hackintosh.

I bought a computer last week. I want it for working producing audio and video but I want also for playing games sometimes. Thats why I started learning about hackintosh: I wanted a dual boot pc with windows and mac. I bought two differents ssd disk and I chose the pcu, motherboard,etc thinking on the compatibility with hackintosh.

I installed windows in the main harddisk and Idownloaded the sonoma image from olarila. I installed mac in the other harddisk and I was surprised for the results, all was incredible well and macOS works nice. But when I copied the EFI folder to the mac partition I think there is the problem: I restarted the computer and I was not able to start windows. That is my headache.

I am looking for a solution for two days: I tried to configure bios but nothing results. I tried to restore Windows from the prendrive and nothing, I had to reinstall, I didnt find how to restore windows boot even I could open de windows partition from macOS.

In that moment I did not what I did that this problem happened, but when I come back to macOS and I tried to modify EFI I find out that was mounting the opencore partition that does something to windows booting, because I had to reinstall windows...

I dont know if Its an easy to resolve problem or not. Someone has the same problem? I dint find in the forum.

If you could help me I was gratefully.

That s my computer:

- MSI B760 gaming plus wifi

- Intel core i9-14900KF 3.2/6 Ghz
- Radeon RX6800
- Kingston FURY Beast DDR5 6000MHz 2x32 Gb CL 30 AMD
- Acer Predator GM7 2TB SSD M.2 PCI Express 4.0 NVme

Certainly some Windows boot files are on this partition too.

You can disconnect the SSD from the Mac, install Windows and then connect the Mac SSD again. Set the SSD with OpenCore/Clover as primary in the Bios/UEFI and the bootloader will manage what you need and leave each system with its separate files.

I managed to solve the issue, in case it helps anyone: after copying the EFI, right after installing macOS, mounting OpenCore, I replaced the EFI on the boot disk with the one I already had, and of course, the Windows folder got deleted. I had to copy the boot folder and the OC folder inside the EFI folder without deleting the Windows one, and everything worked perfectly ☺️
