An error occurred while trying to access the startup disk settings.

Hi guys,
While attempting to change some of my settings through Control Panel running Boot Camp control panel applet I received an error message. It declined my recommended settings, as I have no such administrative privileges.
Have a look at the error message below. How can I get a remedy of this issue?
Please help.
Thanks in advance.

You may not have privileges to change the startup disk. Make sure you have administrative privileges and try again.
