Here is the problem. I burned a Ubuntu Installation disk and ubuntu usb. I used Ubuntu 12.04 amd64. My computer is 64bit.
Here is what happens: When computer starts, it boots from the usb properly. Displays the menu, but when I click either install or just run Ubuntu without installation I face black screen and nothing happens. The same happens when I boot from Ubuntu disk. I tried reinstalling usb, nothing changed.
Any help is highly appreciated. I really want to escape Windows 8.
