I start out with a 1TB Sata SSD and the first partition on the drive is a Windows EFI partition then Windows then Manjaro root and Manjaro home... these are dual booting fine with Grub2. I want to use Grub to chain load Opencore so all three OSs can be on the Grub menu and I don't get any kext etc injection from Opencore in to Windows and Manjaro.
Now if I use Disk Utility from a macOS Catalina USB installer and clone in a macOS installation that is working on another drive this causes the Windows EFI partition to get deleted. Why is this? Even if I first had created a second 200MiB EFI just for macOS on the drive in a partition just before where macOS will be cloned in to (and set its flags to boot, esp).
If I start with macOS on the drive first and then clone in the Windows/Manjaro partitions using Macrium no EFI partition is deleted and everything works... yes even with two EFI partitions on the drive and both are labelled: boot, esp.
So why does cloning macOS to a drive that already has Windows delete the Windows EFI partition and anyway do I need both EFI partitions or will Windows 10, Manjaro and Catalina/Opencore bootloaders co-exist just fine on the one EFI partition? Will Windows or other OS updates break things maybe?
