I'm not exactly an expert when it comes to linux.
Anyway, I'm trying to install Ubuntu Server 14.04.1 onto an old machine I use as a test platform. It will reach the screen that gives me the options to install Ubuntu, check disk etc but then it freezes. I let it sit for maybe 3 or so minutes then it gave me green gibberish text on the top of the screen. Not sure exactly what's going on. The desktop boots fine with PFsense on the HDD.
