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.

You can try pressing F6 in the boot screen of the image and selecting the nomodeset option. Other options added may be necessary.
