The Ubuntu live-cds normally don’t have the BCM4331 drivers installed by default. We’ll need to boot off a Ubuntu live-cd several times. If so, stop reading immediately! In this tutorial, we are doing it the legacy way. Even though it might be a bit complicated, but EFI (or UEFI) is superior in every way. If I ever have to configure another machine, I think I’ll use EFI. I didn’t know much about EFI, so I didn’t pick this way, though things are different now. Optional: a machine with Windows installed to create the Windows 10 USB installer (even a virtual machine with WinXP would work).MacOS pre-installed to an external HDD (optional iff you can figure out and download the correct boot camp support software package online.Ubuntu disk image (to make USB storage devices into live-cds).

2GB (or more) USB storage device (optional, since we can always use the one above, but we’ll need to create a live-cd more than once).8GB (or more) USB storage device (like a USB flash drive).Windows 10 disk image (installation iso file).I don’t want to go through the same thing again without knowing the details. This post is meant to document the entire experience. I’ve spend several days doing this, so I hate to forget how it was done. It may not be the best way, but it’s how I did it. Later, I decided to add Windows 10 to the internal HDD. I have MacOS ElCapitan installed on an external HDD. Initially, I had the entire disk occupied by a Ubuntu 16.04 installation. I have a 2011 mac mini, with one internal HDD. Easy, right? WRONG! The task of installing Windows next to a pre-existing Ubuntu installation on an old Mac Mini could be painfully long.
