I have mamaged to get bt 3 to boot from USB, but after the logon screen it just hangs on a black screen with a non blinking cursor, i have let it sit for 15 mins and does not move, nor does 'ctrl alt numplus' do anything, any suggestions please? i have also tried every mode, same thing, startx-same,config-same, the live cd worked fine. i have also searched the whole site for an answer and saw none,, thanks
