  • Windows 8 will support UEFI and most systems that contains UEFI functions should work with Windows 8. I suggest try run Windows 8 Release Preview on your system and if you received any error , please post it here.

  • Only the 64Bit Version support UEFI. But most board offer a BIOS compatibility mode. Make sure this setting is set to install a 32Bit Windows.

  • According to this document:

    http://msdn.microsoft.com/en-us/windows/hardware/gg463149.aspx

     only 64-bit versions on Vista, Win7 & Win8 support native UEFI mode. For 32-bit we'll have to use UEFI CSM mode.

    that's what I already told you 1 week ago.

  • Native UEFI mode is supported on Windows 8 for both WinRT and SoC-based hardware, however both of these installation options are expected to be OEM based and wont make it into the market aside from being preinstalled on devices.  Otherwise you'll be installing to your desktop/laptop/tablet, which as previously mentioned, should be x64.

  • What functionality diferences would end users see between a Win8 UEFI 32bit vs 64bit? I believe mesured boot is one of those features but I am not sure because I can not find much in the way of documentation.

  • None that I am aware of, Measured Boot is a function of the TPM chip which can be present in an x86 UEFI-based system.
