Good, because this is the point where you should stop, read the thread on how to report bug reports, execute sudo nvidia-bug-report.sh on a terminal and upload the file here.
You can install the package pastebinit to help you with that.
Because obviously something went wrong, and instead of trying different installation methods we should try to solve the problem you encountered.
additional related question:
Once I installed the Ubuntu desktop the system booted up into the X GUI by default. How can I configure it to boot to a command line so I can start and stop X manually.
I really appreciate your assistance here.
You can take out gdm/kdm/xdm of your default runlevel.
You can either use a GUI for this, or the
sudo update-rc.d -f <initfilename> remove
You find those files in /etc/init.d/, you are searching for either gdm, kdm or xdm.
Afterwards you can start them with
sudo /etc/init.d/<scriptname> start
from a console.
