Yup, that's how it feels! Banging my head on a wall.
Downloads went well. MD5 sums checked. Burned two live CDs. Neither one boots to Linux.
Both CDs stall out at - I guess - the last step. Dark screen with a prompt for something "login:" There is not a lot of time to read. Left to itself, screen goes totally dark with no prompt. Tried to give "Enter" (blank password) and prompt returns. Again time is short. After three "Enter" attempts, screen goes dark with no prompt.
I see no info at Mandriva site. Why would they put that in a trial CD?
