My notebook did a nosedive at the weekend when the battery had a catastrophic failure, ie 98% to flat in an instant. Following this, Windows kept running CHKDSK on the drive at every boot, reported no problems and carried on. I forced a full CHKDSK, which failed to cure the problem, and was followed by the system-generated CHKDSK. The evnts log reported the drive as corrupt, but everything was working fine - apart from the irritating boot problem. I used TI8 to restore the drive, problem solved. There may have been another way, but this worked, was quick and faultless. Thanks for providing me such a good lifeline guys.
