Yesterday my laptop ran out of battery and turned off then when I turned it back on I recieved a black screen with white letters saying... We apologize for the inconvenince, but Windows did not start successfully. A recent hardware or software change might have caused this.if youre computer stopped responding, restarted unexpectedly, or was automatically shut down to protect your files and folders, choose Last Known Good Configuration to revert to the most recent settings that worked. If a previous startup attempt was interrupted due to a power failure or because the Power or Reset button was pressed, or if you arent sure what caused the problem, choose Start windows normally.....Then it gives me options to choose, safe mod, safe mode with networking,safe mode with command prompt, last known good configuration (your most recent settings that worked) and start windows normally...i already chose all of the choices and the computer gets restarted and the message appears again I dont know what to do and also before the message appears there is a f9=change boot device order and a f10=BIOS setup options...i dont know what to do I dont have a disc or anything can you please help me and my laptop is a windows xp. Can you please give me step by step instructions on what to do? Thank you very much
