Well, I tried reformatting the drive to use MBR; but that had no effect. So, it doesn't appear to be a GPT issue.
Branden, based on the fact that we do not have support for any Linux flavor, if you have any question regarding this motherboard and Operating system combination, you would need to forward your inquiry to Linux* distribution support community for further assistance.
I would like to inform you that booting from a GPT or an MBR partition will be define by the OS.
If you created a GPT partition and then installed Fedora, I would recommend you to format the drive and reinstall the OS, without any partition.
Here is a thread that I found just in case you need addition information https://communities.intel.com/thread/43629
