(Solved) Sabertooth Z87 BIOS Boot Problem. Not Recognizing Windows Intallations

I keep getting this error:

"The systems found unauthorized changes on the firmware, operating system, or UEFI drivers.

Press to run the next boot device, or enter directly into the BIOS setup if there are no other boot devices installed.

Go to BIOS Setup> Advanced> Boot and change the current boot device into other secured boot devices."

I have to press N and then select the installation from the Windows boot menu.
Has anyone seen and solved this problem? I want to Update my BIOS but it looks like it's no longer being support on the ASUS website.

Hi waynerdpkrebs

In the bios on the boot tab set "Secure Boot" to "Other Os" this should solve the problem.

Thanks for the tip. I'll try it when I get home.

Yes, that took care of it. Thanks!!!
I would like to know what caused it though.

Thanks again, Nate.

You're welcome

I'm not sure what causes it but I get the same message if secure boot is not set to other os.
