Hey Balkano91,
Thanks for the question. I understand you are experiencing issues installing Windows with Boot Camp. The error message you described is outlines in the Installation Setup guide. You may want to check to make sure you're logged in as an administrator:

If you have problems installing Windows
If you have problems installing Windows, try the following solutions.
If you get a message saying “Installer Disc Not Found” when installing Windows
Make sure you’re logged in to OS X as an administrator.
If Windows doesn’t install properly
Verify that you’re using an original, full version of the 64-bit version of Windows 7 Home Premium, Windows 7 Professional, Windows 7 Ultimate, Windows 8, or Windows 8 Pro.
Restart your Mac and hold down the Option key until one or more disk icons appear on your screen. Insert the Windows installation disc into the optical drive or insert the USB flash drive with Windows into a USB port on your Mac. Select the Windows installation disk icon, then click the arrow beneath it. Quickly press any key on your keyboard to start the installer. Follow the onscreen instructions to repair or reinstall Windows.
If the Windows installer isn’t responding
Be sure you are using the original keyboard and mouse that came with your Mac.
If you’re using an Apple mouse, the Windows installer may not respond if the mouse is connected directly to your Mac. Connect the mouse to the USB port on your keyboard.
If you insert the wrong disc during installation
Eject the disc by holding down the Eject key on your keyboard while restarting your Mac.
Thanks,
Matt M.
