[SOLVED] Failed to install override security policy

Question

Hi,
I am trying to install Arch linux in UEFI in a dual boot setup with Windows 8.1. I already have the Windows OS installed, but every time I go to boot from the Arch installation CD I made using the latest .iso download (2013.12.01), I get the following:
ERROR
Failed to install override security policy: (14) not found
I hit return on the "OK", (the only available option), and the error reappears once again. After I hit return for a second time, the installation quits and I am returned to a normal Windows boot. This error happens right at the very start, I literally tell my computer to boot from the CD drive and then straight away the error appears.
I have tried the solution suggested here:
https://bbs.archlinux.org/viewtopic.php?id=169354
(i.e. replacing the bootx64.efi with the loader.efi file (but renamed of course), in the EFI/BOOT/ directory of the iso), and I have tried using other versions of the iso (specifically 2013.10.01) as well as re downloading and re burning the most recent iso. All of these have been to no avail.
I am running an ASUS Sabbertooth 990FX (Rev 1.01), which I know to be an UEFI board. Also, I was able to install Windows 8.1 in UEFI just fine.
Any thoughts about what the problem may be?
PS: Merry Christmas to you all!

--- SOLUTION ---
Download the Arch Linux variant of rEFInd, from http://www.rodsbooks.com/refind/getting.html. Then, install as per the instructions for you particular operating system and needs; follow the following: http://www.rodsbooks.com/refind/installing.html.
Reboot. Next time your computer starts, after the POST is completed, instead of booting into your normal operating system/boot loader, rEFInd should load instead. It will search for bootable media and operating systems automatically, and present you with a list of options. Choose the one corresponding to your CD/DVD/flash drive (depending on your installation medium). It should then boot in UEFI.
Once you are prompted with a command shell, type the commands:
# mount -t efivarfs efivarfs /sys/firmware/efi/efivars # ignore if already mounted
# efivar -l
If a list of variables is displayed, then you know you have succeeded in booting the installation media in UEFI!
Hope this helps some people...

Thanks for the response Lone_Wolf.
I had a good old rummage through the "UEFI BIOS setup" for my motherboard (ASUS Sabertooth 990FX rev 1.01), and found no option to either disable nor enable Secure Boot, which I found rather odd, so I did some searching online and found this quote:
"I've recently bought an ASUS Sabertooth 990FX, which is a uefi
motherboard.
Secure boot cannot be ENabled."
from: http://comments.gmane.org/gmane.linux.mageia.user/8143
Intrigued, I then done some more searching, and came to opening up Windows System Information, to see if I had Secure Boot enabled or not already. The result (as shown in the below screenshot), is that Secure Boot is "Unsupported", which means that my "PC does not support Secure Boot or is a Legacy (BIOS) installed Windows". Since I am running Windows already in UEFI, this means that my motherboard indeed does not support Secure Boot, and hence there is no need for me to disable it.

I will send a quick email to ASUS to confirm this finding, but it certainly seems like Secure Boot is not an option that I have, and hence I have no need to disable it in the first place.
Thanks anyway for the response,
