Hi, I am unable to boot from DVD or CD. I'm running Windows Vista dual booted with Mandriva 2010 Powerpack on a Dell Desktop Inspiron 530S. I'm trying to boot KNOPPIX_V6.2.1 DVD-2010-01-03 and same except CD. I get the boot-menu and select "boot from CDROM" then get a message that " no boot device available press Enter again".
Following is listing for "lspci -v":
