I have some queries regarding configuring a triple boot setup.
You should install a bootloader to manage multiple OS installations on separate drives during triple boot setup. For your configuration, I recommend following the order: Windows 10 Pro → Mac OSX High Sierra → Ubuntu Studio → Unbuntu Studio. This ensures each OS boots correctly from its designated drive.
Windows 10 doesn't integrate well with multi-boot setups. You'll need GRUB, but it gets overwritten often by the Windows boot manager during updates, causing frequent resets. It's safer to use those drives as standalone Linux installations and activate them via the boot menu when needed.
You require a bootloader, simply install Ubuntu last and it will set up a package named grub on its storage, then start from that drive. Previous method: incorrect, Windows only updates grub to its own partition, keep grub on the Linux partition, the old bootloader stays on the Windows disk.
Here are some alternatives:
1) Choose one drive, set Windows as the OS, disconnect that drive.
Set up another drive with macOS, leave it connected.
Use the built-in Boot Override Menu on your boards to select the desired drive for booting.
This approach keeps each operating system separate and ensures installation order doesn<|pad|> can be ignored.
Note: Later you can add Windows and macOS to GRUB for a unified menu.
2) Keep all drives connected. Install Windows first, then Linux, finally macOS without disconnecting any drive.
Allow GRUB and OpenCore to recognize other operating systems and add them to their boot menus.
This method is risky—GRUB may detect Windows and install itself into the Windows partition, potentially overwriting your Linux installation.
Remember: Always install Windows before any other OS, as the boot manager won’t detect others unless they’re installed alongside Windows.
