Chkdsk utility error

[kuanchang]

Whenever i use the chkdsk function, it says:

"The type of the file system is NTFS.
Cannot lock current drive.

Chkdsk cannot run because the volume is in use by another process. Would you like to schedule this volume to be checked the next time the system restarts? <Y/N>"

I'm not using any other process and when I press yes, on the reboot, it still doesn't work. Help?

At boot try to go to a command prompt.
Its done the same way as going to safe mode. Press F8
