Using liveUSB I created a bootable USB with Ubuntu 12.10 desktop. When I boot from the USB it always stops at a black screen. How can I tell what's going on and how to fix it?
This happens to me on my HP laptop. For some reason, it just refuses to boot with a usb drive. I tried all sorts of different software to create the liveUSB.
In the end, I had to use a DVD, and it worked fine. Try that. Hopefully it will work.
You can burn a DVD by downloading the operating system iso and burning it to a disk using Brasero or equivalent software.
