    Secure boot or not, you should still have the UEFI option.
    Hi there
    The secure boot only ensures that Windows 8 currently will boot. For W7 you will have to disable that too.

    Secure Boot is disabled and I have tried to follow the Disk data to USB copy and folder moving arounds and renaming e.t.c - I can only try again and hope.

    I'm unable to do anything on it now though as I'm still sorting out the networking at home - been drilling holes and nailing clips to Cat5e cable around the house - at least THAT works :P (connection I'm using to my router on my main desktop) - still need to neaten everything and clean up my mess.

    Every time I've tried to install Windows 7, it either had a 0x0 error (from within Windows 8), could not install with GPT or frozen on the "Windows Starting" logo.



    the above is from an earlier post of yours ,you cant install a duel boot from with in win8, just did a quick read of your info and i think maybe you usb with win7 install on it was not created properly.

    I've figured that - I was desperate at that point.

    I've re-made the USB earlier - same result.

    YouTube video is still processing.

    I have the same problem as above. I have an OEM WIndows 8 pre-installed on a Samsung NP700z5c-S03UK and wanted to install Windows 7 any way I could. I believe I have created a rescue USB correctly on a 16gb USB stick as it seems to boot on the Samsung when pressing F4 however I really don't know if the Samsung is booting from the USB or the existing rescue partition, theres no way of telling that I can see.

    I did this first so that I had a path back in case my windows 7 installation went horribly wrong.

    I have tried a Windows 7 64bit Home Edition DVD and the ISO was supplied by Microsoft directly. Ive also tried writing a UEFI USB windows 7 install following the links and copying files.

    On every attempt to run the installer the computer gets no further than the windows coloured orbs and then freezes the orbs and does no more. If I hit F8 when trying to install Windows 7 and choose safe mode, it always hangs on the disk.sys driver. I have tested the windows 7 install DVD on two other PCs and its fine.

    I've tried booting a recent version of Ubuntu 12.10 from a USB stick, a windows XP Pro DVD (admittedly I didnt think this would work), a Ubuntu 10.04 CD ROM (nor this one) and none of them seem to want to fully start or are not recognised at all.

    I've disabled the fast BIOS and also the UEFI security and still the same.

    I've been on the phone to Samsung 4 time and Microsoft 4 times as they keep bouncing me between each company saying its the others responsibility.

    Microsoft told me at some point that the only way this would work is if I fully removed Windows 8 and reformatted the entire drive removing the GPT partitions. If only I could boot into something to allow me to clean down the drive. Any suggestions?

    PS. I should mention that the Samsung representative asked me to change the BIOS boot order so that the USB HDD was at the top when trying to recover using F4 and the USB recovery volume. I asked him how we could be sure that it was indeed the USB that it was booting from and he said "look for the LED on the USB stick" of which I had none and then he conceded that he didn't know if it was indeed booting from the USB.

    NOTE: Check your manufacturer's uEFI BIOS manual for settings.

    Boot the Windows 7 DVD in uEFI mode.
