Recently, I got an issue with my OpenCore EFI partition on my Hackintosh system. I messed up the config.plist and it makes my macOS Catalina Hackintosh won’t boot properly. Fortunately, I have another hard drive with Windows 10 installed on it. So, I can edit my config.plist in the EFI partition and now it works again.
Update!!
By default, you cannot see the macOS EFI partition from Windows Explorer, even if your macOS hard drive is connected to your PC. But, there is an easy way to mount the macOS EFI partition under Windows 10. I will show you how to do this in a moment.
Mount the EFI partition on Windows 10
Step 3: Dual-Boot Mac OS and Windows 10 using Clover. The last step is be able to boot boot Windows 10 and Mac OS using Clover EFI Bootloader to do that follow Step 5 & 6 of this guide: Hackintosh Dual Boot Windows 10 and macOS High Sierra (Same Drive) Hackintosh Dual Boot Windows 10 and macOS High Sierra (Same Drive). In this post I’m gonna show you how to make Hackintosh Bootable USB Drive on Windows without Distro. Without distro means we gonna make a Hackintosh Bootable U S Drive for Vanilla Installation method. This method works on Mac OS X Yosemite, El Capitan, and Mac OS Sierra. As I’ve tried all that OS myself on my low budget Hackintosh PC.
Open Windows 10 command prompt as administrator. And then, run “diskpart” command.

Next, list the disk

As you can see, I have 5 hard drives connected to my PC. In this case, my macOS/Hackintosh disk is Disk 3. Yours might be different. Now I will select disk 3
Output
As you can see, my Disk 3 is now the selected disk. Next, we will show the partitions in Disk 3.
As you can see, there are 4 partitions in Disk 3. In my case, the EFI partition is Partition 1. It is easy to know which one is the EFI partition. The EFI partition volume size is exactly 200 MB.
Now let’s mount the Partition 1 and assign drive letter to it.
Now, open Windows Explorer and you should see your EFI partition is mounted there.
Common Issue
In some cases, Windows 10 users cannot open the mounted EFI partition and got the error:
You don’t currently have permission to access this folder.
In case you get this error, I would recommend you to download Explorer ++ program and then run it as administrator. It can open the EFI folder perfectly without issue.
