I've tried 4 different versions of Ubuntu now and I can't get them to boot. I have tried both universal usb and unetbootin with no luck. I have 2 different usb drives I'm trying to use both 4 gigabytes. Every single time I try to either run Ubuntu without installing or try to install onto harddrive it just starts and the machine powers off and restarts. I have successfully booted on my laptop from both usb drives... why isn't this working on my desktop?
Try checking your boot option during startup, press f2. Then configure the boot media option, and make pendrive as 1st boot media. Make sure it is to boot from pendrive. Thanks
