thanks for reply and help me in my problem time.your idea is ok but this idea dosenot work for me.

i solve my problem ussing(f8) safe mode with nateworking.and go to security tab.in advance satting and give user and adminstrator to full control on my system.

without ussing of safe mode i can`t do editing on ownership and take full control to system.
