Exactly. Canonical has gone out of their way to make sure that you never have to muck around in a terminal or BIOS to install Ubuntu, with their Windows installers and all that. If you run their installer and the first step is "reboot, press F12 (or F2, or DEL, or who knows what else) to enter the BIOS and turn off this security setting - that you have to find on your own - then reboot and run the installer again" instead of "click the Install button" that's a big step backwards. Not to mention the fear some users will have about turning of security, wondering if they're being had.
