    Isn't just better to use the microsoft windows 7 usb tool, which also works with windows 8 iso files?

    Hello Makaveli,

    That will not create a bootable USB flash drive that will install Windows 8 with UEFI.

    Hello Makaveli,

    What's the difference between a normal bootable usb with windows 8 and a bootable usb with windows 8 for UEFI?
    Is the only difference that the UEFI one is listed in the UEFI boot menu?
    Maybe i'm not understanding well the purpose of the bootable usb for UEFI.

    Yep, one will let you install with UEFI (GPT disc), and the other only with "Legacy BIOS" (usual MBR disk).

    (UEFI) (see the external links at the bottom of this one as well for more info about UEFI)

    I'm making now an usb flash drive with Windows 8 Pro for UEFI looking at the tutorial and since i currently have windows 7 x64 and i'm creating a Windows 8 UEFI usb, i need to skip step 11, right?
    So basically i only have to type the command prompt commands and extract the iso to my usb flash drive directory?

    Correct. You would only need to do step 11 if you are creating a Windows 7 x64 USB flash drive.

    NO.

    Since you are creating a Windows 8 Pro flash drive, you would not do step 11.

    Hello Cheesedog, and welcome to Eight Forums.

    Did you post this in the right thread?

    This tutorial makes no mention of the .wim file.
