    "Where do you buy your x64 DVD from?"

    I downloaded Win8 from MSDN.
    F12 is boot selection like asking you if you want to boot from DVD or USB or HDD or Network Boot.
    There is no UEFI option in F12, there must be another <F> for UEFI OS Setup maybe.....


    "The software manufacturer would need to have the software signed by Microsoft"

    I dont follow, please elaborate.

    You are implying that UEFI's SecureBoot have an embedded list of allowed boot loaders?

    If that was the case then why we make 'UEFI Specific OS Setup' for? There shouln't ne a need for it since by intrinsic information it would by default check the current boot loader against its database of allowed boot loaders.

    We are making progress but that doesnt make very much sense.
    I think UEFI doesnt have a built-in boot loader whitelist but instead it learns to allow a new boot loader to run if an UEFI OS Setup prior got installed.

    Won't you agree?

    Ubuntu 12.1 isn't signed by MS, but a UEFI Linux Setup can be installed and SecureBoot will allow it.

    Or perhaps although Linux isnt an MS product still MS signs it?

    And what about other Boot ISO's ? What happend to them? We might want to boot other ISO images that MS isnt aware of, and we also dont want to disbale secure Boot.

    Actually its slipstremed and i didnt want to metnion it.

    I download oit form a greek torrent site and it containes

    Win8 Base
    Win8
    Win8 Pro
    Win8 with Media Center

    both x32 & x64 archs UNTOUCHED as it where from MSDN where they got downloaded from.

    I use that DVD because i have 8 different Win for ALL needs.

    I still dont understand though what this slipstream version has to do with the <F12> Boot Selection Menu.

    Please explain.
