I want to install Linux on an old Mac, specifically Mint XFCE or Debian XFCE, and then flash GOS with one of those operating systems, but I wanted to create a dual boot and I don't know if that's possible. I have created two partitions: one with macOS and another empty one where I want to install Linux, but the last time I installed Linux, the computer wouldn't boot up.
Does anyone know what I have to do to create a dual boot that allows me to choose between using Linux or macOS when I turn on the computer?
