In order to install DragonFlyBSD on a UEFI machine one might want to keep the already installed operating system, in my case Arch Linux, leading to what people usually call dual boot. I won’t describe the DragonFlyBSD installation process, I might in a following article, but just what’s required before and what needs to be done after to get it to boot. Prerequisites So before installing I had a working Linux installation and I’m using the UEFI boot manager from my laptop (an HP Elitebook), to boot it.
