    Hi, any one researched for this for windows 8.1 to save those 350 mb of scarce SSD space ? I know this exists for win 7.

    use diskpart to format it before the installation starting and it wont make this 350mb partition

    shift+f10 to open console
    run diskpart

    You don't need to mod the setup at all. You can do everything you need to do with diskpart, dism, and reagentc commands

    Even with UEFI booting, you only need 3 partitions, EFI, MSR, and your primary.
    You could make a partition text file to import with diskpart, just call it format.txt:
    select disk 0
    cleanconvert gpt
    rem == 1. System partition (ESP) ===================
    create partition efi size=100
    format quick fs=fat32 label="System"
    rem == 2. Microsoft Reserved (MSR) partition =======
    create partition msr size=128
    rem == 3. Windows partition ========================
    create partition primary
    format quick fs=ntfs label="Windows"
    assign letter=c
    Then you also make a script to run the diskpart import, apply the image, and run bcdboot and reagentc:
    call this file runscript.bat:
    @echo off
    echo.&echo === ATTENTION ===
    echo This script will create partitions on Disk 0
    echo It will apply the install.wim to disk 0
    echo All data on Disk 0 will be lost.
    echo.&echo Press any key to continue. ^(To abort - manually power down your system^)
    diskpart /s X:\format.txt
    FOR %%i IN (A B C D E F G H I J K L M N O P Q R S T U V W X Y Z) DO IF EXIST %%i:\Sources\install.wim SET INSTALLWIM=%%i:\Sources
    IF NOT EXIST %INSTALLWIM%\install.wim (echo Cannot find the install.wim file
    echo.&echo Applying Install.wim to C drive
    dism /Apply-Image /ImageFile:"%INSTALLWIM%\install.wim" /ApplyDir:C: /Index:1
    echo.&echo Running bcdboot on C:\Windows to register the boot drive with the system
    C:\Windows\System32\bcdboot C:\Windows
    echo.&echo Registering the recovery tools directory with Windows
    C:\Windows\System32\Reagentc /SetREImage /Path C:\Windows\System32\Recovery /Target C:\Windows
    echo.&echo Script completed. Press any key to exit and reboot...
    Now make a final txt file and call it startnet.cmd
    mount your bootable winpe image (boot.wim index 2 if using existing setup files)
    replace startnet.cmd with the one in the windows\system32\ directory
    *Delete the windows\system32\winpeshl.ini*
    put format.txt and runscript.bat in the root of the mount directory

    I found this stuff out when doing the wimboot stuff

    edit: I'm not 100% on the reagentc stuff... you might have to create another partition just large enough to fit the winre.wim and move it during the script.. I really don't know.
    Stop hovering to collapse... Click to collapse... Hover to expand... Click to expand...

    WPEINT takes a while to load up so if I'm not going to use networking I don't even run this. It makes for quick booting if all you want to do is say, wipe some hdd/ssd's....

    Third party tools like Minitool Partiton Wizard bootable cd might do the job, easily. On the understanding the HDD must be partitioned prior to Windows installation. I use it on a daily basis with no issues so far. :cool2:
