i have a problem installing Kali Linux 1.0.3-i386 with an USB on my Toshiba-NB_500 with Phoenix Bios... Kali istallation says there is a problem "Detecting and mounting the CD-ROM drivers" but, if im installing from an USB, why i need CD-ROM drivers? and in /dev/cdrom says there is nothing... what i need to do to troubleshoot this problem?

Thanks, and sorry if that does not go here.
