    Using an ASUS P8Z77-V Pro motherboard, it's worded slightly differently
    1) In advanced mode after hitting the delete key to get into the UEFI settings, click the boot tab

    2) Scroll down to "secure boot"

    3) Click OS type, and then click Other OS, I am presuming this is another way of saying Secure boot disabled, looking at the description on the right
    Click image for larger version
    Click image for larger version

    4) Click exit in the top right and then click save changes and reset

    Thank you Danspy. I added this motherboard to the Note box for others to reference to help them with.

    I believe it is to check if the Windows bootloader being used is not malware or tampered with, this means GRUB may not work, I have also read somewhere that it is to make sure that the copy of Windows you are using is authentic.

    So if you wanted to run a Linux distro you have to disable the secure boot because of the open source code and not being MS certified if your were using the UEFI bios. With the legacy bios, that's not an issue.

    Yeah, you're right, using the legacy BIOS, there shouldn't be a problem.

    You can install Linux with uEFI enabled, but not with Secure Boot enabled.

    HTG Explains: How Windows 8′s Secure Boot Feature Works & What It Means for Linux - How-To Geek

    Installing Linux

    There’s nothing stopping computers from also shipping with Ubuntu’s certificate. Linux distributions can also publish their own certificate and ask users to install it – or ask them to disable secure boot entirely. Fedora will be paying $99 for Microsoft’s signing services, so Fedora will install on any Windows 8-certified PC with no additional configuration required. Other Linux distributions could also take this route.

    Security Advantages

    The traditional BIOS will boot any software. Normally, your BIOS boots the Windows boot loader or maybe a Linux boot loader, like GRUB. However, it’s possible for malware, such as a rootkit, to replace your boot loader. The rootkit could load your normal operating system with no indication that anything was wrong, staying completely invisible and undetectable on your system. The BIOS doesn’t know the different between malware and a trusted boot loader, so it allows either to boot.

    Windows 8 PCs will ship with Microsoft’s certificate stored in UEFI (and possibly other certificates, depending on the manufacturer). UEFI will check the boot loader before launching it and ensure it’s signed by Microsoft – if a rootkit or another malware program does replace your boot loader, UEFI won’t allow it to boot. This prevents malware from hijacking your boot process and concealing itself from your operating system.

    By seting your uEFI/BIOS firmware, to Secure Boot DISABLED, you can install
    NOTE: Check your manufacturer's uEFI BIOS manual for settings.
