Adding a driver to the boot.wim

I am trying to add a PERC raid driver to a boot.wim from a Microsoft Deployment image using DISM, but I can't get the system to add the driver.

It keeps producing the following errors;

Error: 267

Unable to access the image.
Make sure that the image path and the Windows directory for the image exist and
you have Read permissions on the folder.

The DISM log file can be found at C:\Windows\Logs\DISM\dism.log

I have mounted the .WIM successfully, but it still will not recognize the .wim as being present or accessible to the DISM utility when I try to add the driver.

Attached is the log file from the last attempt. This was done on my company machine as I was getting a file in use error when I tried performing the task on the deployment server.

Anyone have any idea what I am doing wrong?

AFAIK  for the boot.wim there is only 1 index and you are trying to mount index:4? is the source to do this if you are using Windows Deployment Services (not recommended) (use Microsoft deployment Toolkit instead).  In fact I suggest you use the Microsoft Deployment Toolkit for everything image related.

That is exactly what I was missing. Thank you very much.

If I could give you more points I would.  :)

Guess my next industry training is going to be on MDT.
