Then type "attrib c:\\boot.ini +r +s +h" in "Run" and press Enter to set back to the system, hidden and read-only properties, and you're done.

Of course, if it is a single system, we can also right-click "My Computer" → "Properties" to open the "System Properties" dialog box, click "Startup and Recovery" in the "Advanced" tab.
