Install error - check disk

I just bought two new RaspberryPi 3's along with two preloaded 8 GB sandisk micro sd cards. Unfortunately, when I booted up the Pi I got an error stating that the file allocation tables (FAT) did not match.

The error message provides the answer (use check disk), but as a NOOB I had to do a little research to figure out how to fix the problem. I followed the steps provided in the following thread: http://ubuntuforums.org/archive/index.php/t-1005398.html.
