This is why I always unplug the other drive before I install Linux, because the one time I didn’t I couldn’t boot the other OS anymore.
I didn’t format the wrong drive, but the Linux installer automatically detected the existing EFI partition and just overwrote it. Luckily, that was the only issue and I was able to recreate the EFI partition, and it taught me a lesson that I will never forget.
