Hey diplomatt,I am trying to put together a multiboot system (macOS Big Sur, Windows 10, and Ubuntu). I have all three on separate SSDs and only had one SSD connected at a time during the installations.
First, I installed macOS with OpenCore on the macOS SSD.
Second, I installed Windows 10 at UEFI-GPT on a second SSD. Everything works fine up to then.
Third, I installed Ubuntu on a third SSD. I made the installer with Rufus and selected UEFI and GPT. I had two options for the drive format in Rufus - FAT32 and NTFS. I chose FAT32, the default. When I booted into the Linux installer, I deleted all partitions visible partitions and installed Linux on the sole partition. It appeared to install fine.
When I boot up in OpenCore, I have macOS, Windows 10, Untitled, and Reset NVRAM. "Untitled" is my Linux drive. macOS and Windows boot and operate fine.
Hope to get some of your advice too. I am trying to do the same thing but without Ubuntu.
I've currently already got Windows 10 running perfectly fine on an NVME drive, and have a separate NVME drive that I'm reserving for Mac Big Surr. I've done the OpenCore OS installer on a USB drive waiting to be inserted.
I've got 3 other non-OS storage internal drives that have been formatted to ExFAT so I can access them through both operating systems.
Am I correct to unplug the Windows 10 NVME drive while I'm installing Mac OS? Once Mac OS is installed and running, would I be able to plug the Windows 10 NVME drive back in?
What is the process after that to ensure both operating systems work? What about being able to install updates on them as well?
Thanks in advance!
