You can do that in many ways:
2.open nautilus as a root
3.You can add "Open as administrator" as an extension to your right click:
i-Download the nautilus-gksu package for your architecture from either of these 2 locations, and save it in your downloads folder.
ii-On your 64 bit install downloaded nautilus-gksu_2.0.2-5ubuntu2_amd64.deb & extracted right in your Downloads folder
iii-On your 32 bit install downloaded nautilus-gksu_2.0.2-5ubuntu2_i386.deb & again extracted in Downloads folder so terminal command
