    Can't install Windows 8 in UEFI mode


    I am using Windows 8 since release now but just figured out it was never installed in UEFI mode. So I wanted to reinstall it. The first problem I had was I couldnt boot from my DVD I burned the iso file on the Windows 8 setup too created for me, there is no UEFI boot option available.

    Then I created a copy of all files on a 8gb SD card, used bootsect /nt60 x:, again, no UEFI boot option available. My last try was, because I have no USB pen, creating a fat32 partition on one of my usb hdds, again copied all files on it, did a bootsect /nt60 x:, and now I was able to chose UEFI: ... from the boot menu.

    So I booted from it, but then it gave me this error screen, and I don't know why, or what to do now anymore. Any help would be really appreciated.
