I downloaded 12.04.2 LTS and burned the iso to dvd, dropped it into the dvd drive then restarted my computer. Everything worked fine and the install process went thru without any errors UNTIL it got the the reboot process. After it finishes install and it then tells you that you need to reboot in order to use the new installation, I click Reboot and it runs thru the process of ending everything so it can reboot and all of the sections shown during this process all come up as "OK" result but it still "hangs" and the system never fully reboots and it just sits there.
Any idea as to why it hangs on the reboot?
