To install, it's as simple as grabbing Brigadier (opens new window) and running either Brigadier.bat for Windows or mand for macOS. Not required but can help alleviate headaches when Windows erases the BOOT圆4.efi OpenCore uses.

And OpenCore itself does not support MBR based installs so the utility is useless to us Note 2: Using BootCamp utilities from macOS will erase the EFI/BOOT/BOOT圆4.efi file on your EFI, which is needed for booting OpenCore.Reminder: Windows MUST be GPT/GUID based, OpenCore will not boot legacy installs.Example of Windows installer creation: Build a Bootable Windows ISO (opens new window).Note: This guide will not cover the creation of the Windows installer, only the installation of BootCamp drivers.That's where the BootCamp utilities come in. Problem comes in when we try to boot windows and have no way of setting the boot option back to macOS. So a neat feature of OpenCore is the ability to avoid the BIOS entirely and use Startup disk solely for multiboot. # Installing and using BootCamp utilities Windows Startup Disk can't see APFS drives.Booting Windows error: OCB: StartImage failed - Already started.Booting Windows results in BlueScreen or Linux crashes.'You can't change the startup disk to the selected disk' error.Can't find Windows/BootCamp drive in picker.
