    GL704GW UEFI CSM Option and Installing Win10 Pro

    Hi all

    We bought a ROG Strix SCAR II - GL704GW-EV001T and run into trouble to change the CSM Parameters, for making an OEM W10 pro installation.
    As you can see in the pictures, we disabled Secure Boot and looking for the option in the Boot Tab
    But there is no possibilty, there is no CSM (Compability Support Module) option to do that.

    We try Version 302 (21.01.2019) and 303 (27.02.2019) from https://www.asus.com/Laptops/ROG-Str...Desk_Download/

    How can we make that change?

    Any help would be appreciated

    Thanks in advance,

    Hi,

    Welcome to the forums and thanks for all the screenshots!

    If you're booting to a UEFI supported drive like the Win10 Pro installation, it's not necessary to enable 'launch CSM' (which you would use for non-UEFI supported installation media like Windows 7), so just tap the 'ESC' key after powering up to select your media in the boot menu.
    If you plug in your boot media first before entering the bios, you can also change the boot order in the bios if you prefer.

    =================

    W10 installation options

    Hi cl-Albert

    Thanks for you reply.

    OK, so if we do UEFI, how can we prevent that the system still use the embedded W10 Home Key.
    The installation starts normal, but we should have after selection of installation-language the setting for enter an product key and/or if you skip the selection of Windows Edition.

    We always go directly to formating the disc and after we have a W10 Home again.

    Picture 1 - W10_normal
    Picture 2 - W10_ASUS

    Maybe we just don't see the option, where we can disable the embedded key.

    Thanks again for any suggestions.

    Best regards,
    Inter

    Hi Inter83,

    Unfortunately, not sure what will be the best way to resolve this since it's not a common issue that I normally run across and am not as familiar with it.

    If you don't mind upgrading to Win10 Pro from the Win10 Home installation, guessing that would work if you just run the setup again from inside Win10 Home, but I could be wrong.
    Microsoft's website below has information about upgrading from Win10 Home to Win10 Pro as well with a Win10 Pro product key .
    https://support.microsoft.com/en-us/help/12384/windows-10-upgrading-home-to-pro


    Otherwise, not sure what options are available for installation media these days, but remember a time when you could download Win10 Pro to install Win10 Pro regardless of the embedded Win10 Home key, so wondering if you can still do this, and if your installation media may contain both Win10 Home as well as Win10 Pro .
    If you can download the Win10 Pro installation media that doesn't include or install Win10 Home, then guessing this could also be a solution.

    Anyway, hopefully others can provide better suggestions if mine are not helpful or correct.

    Solution

    Hi cl-Albert

    Thanks again for you investigation.

    If we run the setup in Windows, it's the same. After a reboot it switch back to W10-Home
    And unfortunately for upgrade the system to W10 pro you cannot use OEM key.
    Upgrading with Store is not possible, because the License is in that case bound to an Microsoft Account.

    So, we made some excurse in UEFI, bootoptions, Microsoft, and reading lots of forumposts... :-/

    The solution (if some others have that problem):
    You need:
    - USB-Flashdrive
    - W10pro DVD or .iso
    - Rufus

    BEFORE START - MAKE BACKUP - IF YOU HAVE NO IDEA, WHAT YOU DO - DON'T DO IT.
    You will erase the existing installation - secure the folders like cl-Albert wrote before!

    1.) Extract W10 Installation Media into a folder or Copy all from Install-Media in that Folder.
    2.) Add a File in /sources called ei.cfg
    Edit File with Editor:
    [EditionID]
    Professional
    [Channel]
    Retail
    (=> here we fix Editon to PRO)
    3.) add a File in /sources called PID.txt
    Edit File with Editor:
    [PID]
    Value=XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
    (=> THIS WILL BE THE OEM SERIAL OF W10PRO and override embedded W10Home)
    4.) get software Rufus https://rufus.ie
    Install or use portable
    5.) Put in a usb-flashdrive
    Run Rufus
    Drive: pick the usb-flashdrive
    Klick on advanced settings
    Start: UEFI:NTFS (you must use first advanced settings, then you can pick this )
    Format: Give the usb-flashdrive a name
    Run START
    6.) Copy after it finished ALL files from the first created folder of W10 Install Media on the usb-flashdrive
    7.) Override autorun.inf if asked
    8.) Boot ASUS with hold F2 to BIOS
    9.) disable secure boot and fast boot - see pictures at startpost
    10.) select usb-flashdrive for boot
    11.) do the installation
    12.) enable secureboot and fast boot again

    With this setting you can override UEFI embedded key.
    Here some good links, for explaination.
    important; you cannot use Fat32, because two files are too big for that... and Win7 Boot Tool isn not recognised in ASUS Boot.
