Outdated BootCamp drivers(generally ver 6.0 will come with brigadier, BootCamp Utility in macOS provides newer version like ver 6.1).# Windows Startup Disk can't see APFS drives
See Configuration.pdf (opens new window) and Can't find Windows/BootCamp drive in picker entry for more details. This can be avoided by either move Windows to it's own drive or adding a custom drive path under BlessOverride. This is due to OpenCore getting confused when trying to boot Windows and accidentally thinking it's booting OpenCore. # Booting Windows error: OCB: StartImage failed - Already started If your firmware is quite old(generally 2013 and older), you'll want to enable ProtectMemoryRegions.ĭue to the variations of firmwares from vendor to vendor, you'll need to play around with the combination of these 3 quirks and see which works best. Check your logs whether your firmware supports Memory Attribute Tables(generally seen on 2018 firmwares and newer)įor Z390 and newer motherboards, you'll also want to enable ProtectUefiServices to ensure OpenCore's patches are applying correctly. This is due to alignment issues, make sure SyncRuntimePermissions is enabled on firmwares supporting MATs. # Booting Windows results in BlueScreen or Linux crashes PlatformInfo -> Generic -> AdviseFeatures -> True.To fix the latter, we need to enable this quirk: To fix the former, either disable or uninstall these tools. Irregular partition setup of the Windows drive, specifically that the EFI is not the first partition.# "You can't change the startup disk to the selected disk" error OpenCore should pick up on this entry automatically Note: As of OpenCore 0.5.9, this no longer needs to be specified.Misc -> BlessOverride -> \EFI\Microsoft\Boot\bootmgfw.efi If Windows and OpenCore's boot loaders are on the same drive, you'll need to add a BlessOverride entry: Make sure Misc -> Security -> ScanPolicy is set to 0 to show all drives.This also means MasterBootRecord/Hybrid partitions are also broken so you'll need to format the drive you want to install onto with DiskUtility. Most installs now are UEFI based but those made by BootCamp Assistant in macOS are legacy based, so you'll have to find other means to make an installer(Google's your friend). So with OpenCore, we have to note that legacy Windows installs are not supported, only UEFI. # Can't find Windows/BootCamp drive in picker BootCamp/Drivers/Broadcom/BroadcomBluetooth.
