I (foolishly) scheduled chkdsk to run at next windows startup, eight hours later, I rebooted as I ned to get on with work but it's started again, but at the beginning - How do I stop it? It had been running for over eight hours and had got to 30% of stage 4 of 5, but I need to get work done so I rebooted, but it has now started again ... at the beginning. It did not give me the option to press any key within 7 seconds. I can't stop it and it keeps restarting at the beginning every time I reboot. I didn't realise it would take sooooo loooong to run - Microsoft should surely provide a warning that you are going to loose at least a day's work. Any help would be most appreciated - I need to get work done, not sit and watch a computer that is going to take over seven hours and possibly a day to start. Many thanks in advance 1 person needs an answerI do too
