I downloaded the latest version of Ubuntu Desktop for i386 since I like to run it on an older computer which does not support 64bit. I successfully following this tutorial on how to create a bootable USB stick. The computer boots the stick as expected and stops to let me choose between Try Ubuntu and Install Ubuntu as shown in the screenshot below.
I have chosen the Try Ubuntu option. The option dialog disappears as the menu bar does. I waited for more then two hours but all I see is the background image and the mouse cursor which can be moved. When I press the power switch on the computer a menu pops up which offers me options to either shutdown or restart the computer.
How can I analyze the boot process in order to find out why the Try Ubuntu feature does not work?
