i just burned the dvd to test backbox, i never used it before so... after burning the iso i started my laptop, all i get is:
Authentication failure
Authentication failure
Authentication failure
Authentication failure
Authentication failure
it gives me this error like 6 to 8 times, after that i press ctrl+alt+del and it asks me to remove the cd press enter and it restarts my laptop.
and that's it... not even the livcd works? what am i doing wrong ?
