mdt OS image is not creating, how to fix that?

  • 772

When I try to import windows 10 image to MDT, I am getting below error. Even with local folder or with mounted iso file.

enter image description here

Please suggest how to fix this,

The error is "THe specified source directory doesn't contain install.wim" But this is the iso file I downloaded from msdn and working with manual install of OS.

    MDT is unable to process ESD files and is not aware of install.esd files. To fix your issue, you must convert the install.esd into an install.wim file.

    ESD files are included in modern Windows installs and contains a compression algorithm that makes them read only with DISM. They are also called push button reset recovery images. The compression is much better than a normal WIM file.

    As a best practice to ensure that your deployment share isn't too big, make sure you delete the install.esd file after you are finished with it.

    If you want to import multiple indexes into MDT, you will need to run step 2 for every image index you want in the final install.wim. DISM is intelligent enough to recognise an existing install.wim and it will add an additional index to it.

    How to Fix

    To use modern install images (ESD Files):

    1. Copy the contents of your ISO to a read/write folder.
    2. Use DISM to extract the ESD compressed WIM file Index(s) of your choice to an Install.WIM in the sources directory of the extracted ISO.
      It is best practice to remove the install.esd file after you have finished exporting the image. This prevents the deployment share from being too big.
    3. Use MDT to import the extracted installer ISO with the converted install.wim.
