Hey guys,

I had a lot of problems a couple of weeks back getting Windows installed via triple boot on my 2TB NVMe SSD.
Now that I have only macOS and Linux running on it I dug up a 500GB Samsung 860 EVO SATA SSD and installed Windows on that while having the M.2 SSD uninstalled from my System (so that no conflicting **** happens where the 16MB W10 partition lands on the NVMe drive etc.) I now have Windows installed on the SATA SSD and reinstalled my M.2 SSD onto my mobo, my OpenCore option has vanished from my BIOS.
I know that the whole Bootstrap thing in the guide was there to avoid that happening, but I wanted to have the install run as clean and isolated as possible. When I select the boot option UEFI OS on my NVMe SSD I can still boot into Linux, but macOS no more.
So the question is: How do I mount my EFI and get OpenCore to be the priority? Does anything need to be deleted on the Windows side of things?
Please fill me in.

Thanks in advance!
 
UPDATE: So I tried to create a bootable USB with my previous EFI from an other stick but alas I get put into the GRUB rescue mode with no other results.
I am seriously confused and frustrated.
I just can’t get into OpenCore and macOS.
Where do I go next?image.jpg
