Disable the BDE Partition


  • How do you disable the BDE partition from being created with a Lite Touch Windows 2008R2 deployment?  I dont want to create the 300MB drive for Bitlocker and can not figure out how to get rid of it.

    Any help would be appreciated...

  • I did that with no luck.  Here is my customsettings.ini

  • try disabling the bitlocker task in general in your ts

  • I tried that as well.  It is disabled.

  • Are you sure you are using the correct customsettings.ini
    Check the log te ensure that it reads the correct customsettings.ini
    Update the deployment share.

  • I am using the one in "\depoyment\control".  I have also updated the share with no luck.

    Where can I find the log file at?

  • It should be under c:\minint\smsosd\osdlogs. Look for the Bdd.log file if possible post your log here hand we can try see whats happening.

    If you dont find it on C:\ you may need to start the deployment again. In Windows PE the logs will initially be on the X:\ but will be moved to the C:\ once the drive is partitioned and formated.

  • try

  • Well spotted Robert I did not see he had it in lower case

    That should do the trick

  • Thanks.  I am trying it now.  I will update once I am done.

  • Made the change to using all caps, and it still didn't work. 

    Any other suggestions? 

    Thanks for all your help.

  • Then we will need to see the log it should be on c:\minint\smsosd\osdlogs\bdd.log

  • The parameter is "CASE SENSITIVE". It's like this:


    And run an "update" to the deployment share after the change.

  • Appears looking through the code that DoNotCreateExtraPatition is *not* case sensitive.
    So we need to see the bdd.log file to see what ZTIDiskPart is doing.
    Can you upload the log file to a public location?

  • I will be more than happy to upload it. 

    Where should I upload it to?

  • I know this may sound silly but thought i would ask as sometimes we forget these steps:

    edit the customsettings.ini file, update the deployementshare, and if using WDS replace the current boot image with the updated one?

    In your bdd.log file you want to look for this line:

    DiskPart>Create Partition Primary Size=300

    That's your system partition that the setting above is supposed to get rid of.

    Also check this line in your log to make sure the proper customsettings.ini is being used:

    Using DEFAULT VALUE: Ini file = \\yourserver\share\customsettings.ini

  • What exactly did you do to get it working? I have the problem you describe and have done the same steps but the partition is still being created.

  • snip from my customsettings.ini

    and I dont get the extrapartitions with this. But in remark to this, we only creat MBR disks. So on new hardware, ex IBM that uses UEFI and want to have GPT disks we have enforced to use MBR anyway. We do this by renaming the file bootmgfw.efi under RemoteInstall\Boot\x64. Then the server cannot boot into UEFI PXE and it will not enforce GPT disks..Sorry..this is another topic but can be related to extra partitions..

  • I have the exact issue you resolved with disabling the bootmgfw.efi... I have Lenovo 1578H3U desktops.  How did you disable it?  MDTK 2012 keeps using a GPT partition even though I am telling it to use a MBR.  When it does this the system can't boot unless I use a boot dvd which I start my image with and then it gets to Windows no problem and everything is great from there.  I tried using EASYBCD to fix it but no good.   Every once in a while it does use a MBR partition and everything works perfectly.  Where is that path you mentioned?

  • If MDT is creating a GPT disk, it is detecting that the computer has booted in UEFI mode.  If this isn't what you want, you will need to turn off UEFI in the computer's BIOS, or choose a non-UEFI boot option when booting the computer.

  • every bios is different but you should switch the pci rom priority from efi compatible to legacy

  • I contacted Lenovo and they are telling me there is no way to disable UEFI within the BIOS.  I don't see anything either.  I'm really ok with using UEFI if it would boot.  But, it won't boot unless I use one of my boot disks I created with MDTK.  Since it looks like I can't do anything about disabling the UEFI maybe I should concentrate my efforts getting my image to boot with GPT.  Do you have any ideas why the boot files aren't being created?

  • I didn't see this option in my BIOS so I contacted Lenovo and they told me it can't be disabled.  Any other ideas?

  • Additonal interesting facts...  I can install Windows 7 and Windows 8 and it automatically installs NTFS with MBR just like it's supposed to.  I can't turn off UEFI with GPT in the BIOS.  Is there a 3rd party BIOS I can reinstall over Lenovo's?  There just has to be a way to overide MDTK and force it to only use MBR regardless of what it detects.  If I could get it to boot I would be ok with GPT but the bootloader is not referencing the OS.  I tried to use EASYBCD but it won't work.  Does anyone have any ideas?
