No, your existing image is fine, if you've got one.
~$ ls -l /media/mmc1/debian-final.img.ext2 -rw-r--r-- 1 user root 1.1G Sep 14 17:35 /media/mmc1/debian-final.img.ext2
I guess I'd better figure out what to do about that message to make it clearer. As for your errors, you need to reboot, open up a terminal, and type: Code: sudo debian and post the errors here.
sudo debian
