haha i found that exact thing b4 i posted my last comment, but it kept asking for my debian cd which is on a usb and i couldnt figure out how to mount it so i just felt tired of it and went on with something else then remembered how to mount usb so i did when it asked but wasnt working and i had leave off to college and when i got back i checked my email to find this and i thought wow how about 1st mount usb then follow directions in link. for any body else looking for the solution:
mount /dev/sdc /media/cdrom *sdc may differ **if your iso is on a usb
then go to link above and follow directions.
lol not as simple as auto with Xubuntu 11 but at least debian 7 is support and is still simple install.
Thanks to all who replied!
