The subject says it all. I've been trying to find alternative operating systems to make my old Mac Mini useful. I had Windows XP on it for a while, but I don't really use XP anymore. I tried making a bootable USB drive with the CHromium Cloud Ready operating system, but the mac doesn't seem to want to boot from the drive. I held down option at startup and tried pressing the left and right arrows, but it kept booting to Leopard which is the only system I currently have installed.
I next tried to install the latest 32 bit version of Ubuntu mate. However, the Mac spits out the DVD when I try to boot from it. After this, the computer boots into Leopard. What am I doing wrong? I heard something about installing another boot manager, but I don't know if that is accessible. Can I run either Cloud Ready or Ubuntu mate on this machine or should I just give up?
