I WAS WORKING ON MY LAPTOP UNTIL THE BATTERY RAN 0UT, I WENT HOME TO CHARGE IT AND NOW EVERYTIME I TURN IT ON, THE COMPAQ SREEN COMES UP AND THE NEXT SREEN JUST SAYS "CANNOT READ DISK PRESS CTRL+ALT+DEL TO RESTART" AND IT DOES THAT EVERY TIME. i WENT INTO SAFE MODE AND SETUP THE DEFUALT CONFIGURATION BUT IT DIDN'T HELP. WHAT COULD IT BE AND WHAT SHOULD I DO? its a compaq presario 2100 if that helps
