HDD detected on W8 UEFI BIOS but not on OS?

I have a hybrid setup. One drive is a 256 GB SSD and the other is a 1 TB HDD. I installed my OS into my SSD and I know this because I had only the SSD hooked up. I added the HDD after the OS was completed. For some reason after I added the HDD the only thing being detected is the SSD. Oddly enough, both drives are detected in the UEFI BIOS but not in the OS.

I'm not sure if this is a plausible factor but if I move the SSD to first priority in the UEFI BIOS boot priority and HDD second I get this screen shown on my monitor: http://i.imgur.com/GR2zcKE.jpg. However, if I move the SSD to second priority and HDD to first then the OS loads. Does that make any sense considering that the SSD has the OS and that the HDD isn't even being read on the OS?

The window on the right is asking me to choose GPT or MBR. Which one do I pick?
