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):
- Copy the contents of your
ISO
to a read/write folder.
- 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.
- Use
MDT
to import the extracted installer ISO with the converted install.wim
.
