I can make a video of this process as it is new and follows corrupting an efi to boot another. If anyone needs it as it is a convaluted process.
Great. If there is a video, it will help me and everyone a lot. I think a lot of people will have the same problem as me

I will have to make it, no one has used this method most see the grey screen as a failure notice. It normally is a failure notice and I will have to make the video, as there is no documented proof of this method,I discovered it by brute Force and chance to get the Dell 7559s to work consistently and correctly with UEFI opencore.

I will try to do as you say. But I look forward to your video. Thanks for your sharing.

Okay here is the demonstration, I'm working on a guide. This video shows proof of the same UEFI efi not working, when I boot directly. It only works when I boot from the grey screen!

I made another partition on my bigsur hdd. I installed clover like this



  1. Install Clover (v4920 till May,2019) on USB:
      --Set install location on USB
      --Click Customize, select:
        Install at EFI section
        Bios0af
        BiosBlockIO
        drivers64/ApfsDriverLoader.efi
        Install RC Scipts to all Bootable partition & Install extra RC Script

This is the only way for it to show up as a legacy device and trigger the 7.
I then added these bios files, instead of the correct ones and used a Open core efi. I click second hard drive and it works.

Now this final step is the hardest and I would recommend getting the gray screen to work properly with a USB first.

so 2 usb we will do the following:
Usb 1: OpenCore (with MacOS and EFI files)
USB 2: Clover

When the operation is successful. Then will convert usb 2 into 1 partition in the hard drive

Here is a screenshot by screenshot tutorial, now it is very important you use this exact clover, as it creates a legacy (7) boot device properly and is before the O.C merger.
