2.Change the BootExecute entry from:
autocheck autochk * /.........
autocheck autochk *
If you have scheduled CHKDSK for multiple volumes, there will be an autocheck entry for each volume. Delete the string from the BootExecute registry value for each volume you do not want checked. If you have NT 4.0, SP2, a new command line utility, CHKNTFS, will assist in preventing repeated CHKDSKs during reboots if the "dirty" bit is set. Type CHKNTFS /? and see KB article Q160963.
