I think it should work. You would be advised to run the Big Sur installer on a spare SSD, not your working drive, so you don't cause any unnecessary issues. Remember that the Big Sur installer like Catalina requires a 16GB USB for the installation files.

Also I believe the AMD patches for OC have been updated, fixing an issue where AMD GPU's ran slower on AMD systems when compared to the same dGPU on an intel system. So you might want to look in to updating the Kernel patches in your config.plist, even if you don't update to Big Sur.

Could be they made changes to OC when Big Sur was released. You may need to upgrade to a newer version if that is the case.

The latest version is still OC 0.7.0, but it may change to 0.7.1 soon, as the developers like to roll out a new version at the beginning of each month. The Dortania guides will change to reflect the new version shortly after it is released.

You will need to create a new OpenCore EFI folder.

Download the latest OC release from here - https://github.com/acidanthera/OpenCorePkg/releases

As previously stated the developers have released a new version today (5 hours ago). So the latest version is now 0.7.1. You may need to give the Dortania site a little time to update their AMD guide.

Access the latest AMD Ryzen guide here - https://dortania.github.io/OpenCore-Install-Guide/AMD/zen.html

You should have most if not all of the ACPI tables. required for your system. But check that nothing has changed.

You will need to update your kexts to the latest versions for Lilu, AppleALC, WhateverGreen, VirtualSMC etc. Use Hackintool app to see which you need and let the app do the work for you.

I use Corpnewt's ProperTree to edit my OC config.plist. Latest version can be downloaded here - https://github.com/corpnewt/ProperTree.

Once you have copied all the kexts, SSDT's drivers and tools etc. to your OC folder I would recommend running the Clean Snapshot feature from within ProperTree. This will add your SSDT's and kexts etc in to your config in the correct order and enabled. So you don't need to do this manually.

Be aware that some patches and kext features in OC have changed, with new fields added. ProperTree should deal with these correctly. But don't simply copy and paste your old entries to the new config.

You will need to use the Sample.plist provided as part of the OC release package, in the Docs folder, as a base for your new config.plist. Then go through the OC Zen guide ensuring you select the parts relevant to your system.

Some of the information you will need will be in your current OC config.plist, such as MLB, ROM, Serial Number etc.

I will remind you again that you need to be wary of copying old settings to your new config.plist as they may have changed, been removed or replaced. So stick to the details shown in the new guide as much as possible.

PM me a link to your current OC EFI and I will see what I can do about creating a new OC 0.7.1 EFI for your AMD system.

You are seeing what I expected you to see.

Did you add the new OC EFI folder to a Big Sur installer?

You might want to check that it works OK with your current macOS drive, before you update to Big Sur.

If the new EFI is working as expected with your Catalina drive, replace the old EFI with the new one. So the system boots from the macOS drive not the USB..

I take it from your previous post the Big Sur installation icon didn’t show on the OC boot screen/GUI.

Good to know the EFI works with your Catalina macOS drive.

Can you boot your Windows 10 disk from the icon on the OpenCore Boot screen?

Not sure why the Big Sur Installation icon would not show. Something for me to think about.

I have PM'd you a revised config.plist with the four extra 'terminal' type icons disabled, so they don't show on the boot screen.

You will need to use the F8 Boot Menu option to boot in to Windows. I added a Windows 10 drive to my rig and it also has problems booting windows from the OC boot screen.

Probably something I haven't added to the config.plist. I will drop you a line when I get the answer sorted.
