    Hello and welcome!

    If your PC doesn't have UEFI BIOS version 2.3.1, it won't support Secure Boot. Basically, this doesn't really matter. It's just telling you that your BIOS doesn't support the Secure Boot feature of Windows 8, which is NOT an actual requirement for your PC. That's a new UEFI BIOS version that wasn't out when 7 was around. All NEW Windows 8 PCs require that to be Windows 8 certified.

    Essentially, just go ahead and install Windows 8. This isn't a concern. Also, for the sake of your sanity, please do a custom install of Windows 8 (you will need to make a bootable DVD or USB flash drive after backing up your personal files elsewhere) over an upgrade. The upgrade will carry over some junk from Windows 7 to 8 that could cause issues down the road. A clean custom install is a squeaky clean version of Windows 8. We have some tutorials here on the forums that tell you in depth about this.

    Windows 8 will install with or without Secure Boot.

    Secure Boot is only on New OEM PC's & New Motherboard's made for Windows 8.
