I needed help badly! A computer here in the office suddenly cannot boot. Error shows that Boot disk failed. At first I thought the hard disk crashed. So I take out the hard disk and put it in my cpu as slave just to make sure the hard disk really crashed. But it works. The hard disk is fine. So I take it back to its cpu but the error still shows. I take out the IDE Cable connected in the CD Rom but the problem still remains. It says there are no Primary Master and Slave. I check the CMOS but it was configured to automatically detect the hard disk. What shall I do?
