Hi guys, previously had a dual boot installation of Windows and macOS, everything worked fine at the time of boot, I select from the
BIOS, not from the OpenCore menu, which system wanted to boot, whether Windows (Windows Boot Manager) or OpenCore, but from one day to the next (I think it was with the Windows update from 1909 to 2004) my boot with opencore disappeared , there is only the Windows one. So I decided to enter the EFI partition of my disk from Windows (with Explorer ++) and copy some files that I had from my EFI partition backup where if the dual boot worked. I did it but it didn't work, OpenCore still didn't appear, so I decided to download GibMacOS and run the script to create a custom USB where I had an EFI created with OpenCore. And just replace the config.plist and my personal OpenCore folders, when using the USB it works, OpenCore appears and Windows Boot Manager also appears, the latter appears 2 times (I suppose one is from the USB and the other is from my disk). There I was able to start macOS successfully and also Windows, so I said, well why not copy all the contents of my EFI folder from my USB to my disk? I did it and it didn't work either, OpenCore doesn't appear! Windows only, what can be the problem? Should I use an application to directly clone the EFI partition? Or what do you recommend? From already thank you very much.
