hi guys

i haven't seen any replies to my broken dependency thread so i assume that i'm done for. but now reverted to reinstalling gusty gibbon on my pc, but the problem is my pc doesn't show setting when i press "ESC", F1, F2, F11 and delete so when restart my pc with a life cd in it just boots normally as if its not there. i don't know what to do to get my normal kubuntu back. please if any onem, any one at all have a faint idea of what i should do please help me out. thank you in advance and thanks to those who took their time reading my last thread, i know you would have told me if you knew the solution.
