    ei.cfg to edit and burn into a dvd


    Hi all,

    I want a Win10 official ISO that allows me to choose between Home and Pro even if the computer has its own key into the mainboard (surely Home).

    To achieve that, I need to edit the ei.cfg file and it works fine.

    But this when I use to install Win 10 from a pendrive, I use Rufus and then edit that file.

    My issue is that I want to burn a DVD with the ei.cfg edited.

    All my software (7zip etc) don't allow me to edit a file inside an ISO and I am afraid that If I decompress the ISO -> edit -> make the ISO I will lost something in the bootable stuff and the installation won't work.

    Also, I am afraid about the UEFI/LEGACY stuff... for USB I know how to to it but with the DVD what will happen? I have to burn two different DVDs one for UEFI and one for LEGACY?

    UltraISO > ISO CD DVD image creator, editor and ISZ DMG DAA UIF to ISO converter - UltraISO can
    extract/create/edit/convert CD and DVD image files directly, make bootable CDs
    and convert ISZ DMG DAA UIF to ISO.

    There is no need to create two DVD discs.

    You do not need either two USB flash drives.

    Option 1: How to create a bootable USB flash drive, that works with both UEFI mode and Legacy BIOS mode.

    USB Flash Drive - Create to Install Windows 10

    OPTION ONE: Use Media Creation Tool to create Bootable Windows 10 USB for Legacy BIOS and UEFI

    This option will use the Media Creation Tool from Microsoft to download an ISO file and create a bootable USB flash drive that is 32-bit, 64-bit, or both, and be used to install Windows 10 with or without UEFI.

    Option 2: How to create a bootable USB flash drive from the Windows 10 ISO image file, that works with both UEFI mode and Legacy BIOS mode.

    - Connect your USB flash drive.
    - Open a command prompt as administrator and type (or copy and paste) the following commands.

    diskpart
    list disk (make note of the USB flash drive disk number)
    select disk # (where # is the USB flash drive disk number)
    clean
    create partition primary
    format quick fs=fat32
    active
    exit

    - Right-click the Windows 10 ISO image file and choose "Mount". If you don’t see mount command from the context menu, go to "Open with" > "Windows Explorer" instead.
    - Copy the files and folders from the mounted Windows 10 ISO image file to the USB flash drive.

    Do it on usb first, then simply burn contents of usb to dvd. Why not just use a pendrive anyway - faster and easier.

    Does not work that way. DVD is not bootable either in UEFI mode or in Legacy BIOS mode.

    Hi guys,

    hang on please... I became confused a little.

    I don't need anything related to the pendrive because I am able to remove the "ei.cfg" from it, and I am also able to make a pendrive that starts in UEFI and in LEGACY.

    Here my issue are two and they are:

    1) to edit an ISO by removing that file "ie.cfg" without any *PAY* software (a freeware one or at least a method to do manually)

    2) if such ISO will be bootable with both UEFI and LEGACY (the ISO I am using are from the Microsoft official site)

    Please help...

    If you have a computer with UEFI firmware embedded Windows 8/8.1/10 product key.

    And if you want to choose which edition of Windows 10 will be installed (see screenshot below).

    Copy the EI.CFG file to the SOURCES folder on the Windows 10 USB flash drive or ISO image file.

    EI.CFG

    Code:
    [Channel]
_Default
[VL]
0
    Before creating the "ei.cfg" file make sure its not "ei.cfg.txt", it must be "ei.cfg".

    You can't find a free program that does not have the save file size limit.

    For example, UltraISO - "Trial version cannot save file above 300MB".

    This will bypass also the problem when a computer is with it's own product key inside the mainboard?

    In such mode it will install the "retail" version?

    You can use Oscdimg which is free - you just have to download the ADK from Microsoft.

    You need to copy a short script to do it - see here for example Update an ISO using PowerShell or just google oscdimg.

    I always put this bit for the bootdata variable just to be sure
    Code:
    # Set the correct boot argument based on availability of boot apps
if (Test-Path "$WorkDir\fwfiles\etfsboot.com") {$BOOTDATA="2#p0,e,b`"$WorkDir\fwfiles\etfsboot.com`"#pEF,e,b`"$WorkDir\fwfiles\efisys.bin`""}
else {$BOOTDATA="1#pEF,e,b`"$WorkDir\fwfiles\efisys.bin`""}

# Make ISO
$command="$ADK\Deployment Tools\$PEArch\Oscdimg\oscdimg.exe"
Write-Host "Creating $ISOPath ..."
&$command  -l:$ISOLabel -h -m -o -u1 -bootdata:$bootdata "$WorkDir\media" "$ISOPath"

    Yes. Yes.

    When installing Windows 10, the Windows setup uses the following priority logic for product keys.

    1. Answer file, either the edition configuration (EI.CFG) file or the product ID (PID.TXT) file.

    2. Product key in the UEFI firmware.

    3. Product key entry screen.

    If a key is supplied, the key is attempted to be use with the image that are available on the media being installed. If there is no product key supplied in the step 1 and step 2, you will get the product key prompt during setup.
