i entered a password on my system and now when i even try to turn (its not even giving me the chance to get into the boot from menu)it on it asks for a password .im inputting the same as i put in initially but it just comes up "password not valid"or something like that (it gives me three attempts and then it just goes to an all black screen with a flashing cursor and nothing works apart from the off button) is there any way to recover this or reset the system? its totally gubbed just now :(
