Q: Can't install OS X Mavericks

OS 10 Mavericks will not install because I get message "This disc is not formatted as OS Extended (Journaled). Use Disc Utility to enable journaling or reformat disc." 

 

I used the Disc Utility and the main hard drive is already marked as OS Extended. 

 

I have an iMac running OS 10.8.5.

 

Any Ideas?
