I'm currently going out of my mind! Is there somebody, please, to help to find my way out of this misery? I can't mount CD/DVD drive in 13.04. If you don't help I'll be forced to go back to... it is even hard for me to type it... to Windows. I've tried with DVD, with music CD, with data CD... nothing. But, I can boot from a CD/DVD drive, it is not a problem. What should I do? Thanks in advance.
