I can't install ubuntu using an external dvd writer/reader, when I'm selecting "install ubuntu inside windows" the screen goes black and dvd is ejected from dvd tray, then if I press anything my pc is rebooting.
I see something like:
acpid: exiting
speech-dispatcher disabled; edit /etc/default/speech-dispatcher
*Asking all remaining processes to terminate... [ OK ]
then the dvd is ejected from the bay.
What's wrong?
