The Windows MCT creates an ISO with an Install.esd file. The TechBench ISO download has an Install.wim file.
I've seen some posts that say the Install.esd file cannot be used with DISM.
I've seen some posts that show a complicated method of using Install.esd with DISM.
I've seen one post that shows DISM with a "SOURCE:ESD: ..." parm (that certainly implies esd files work).
I tried the latter to repair an error that SFC could not fix and got a "The source files could not be found" error. (I don't remember that actual text of the error message, but the logged message was
The source files could not be found; their location must be specified using the /source option to restore the feature. - GetCbsErrorMsg
- Should I download the TechBench version just so I get the .wim file?
- If so, should I burn a disk from that rather than use the mct version (assuming I ever really need the ISO)?
Also, I've seen several comments on the web about putting the Install.wim or Install.esd on the desktop and pointing DISM at it. Why? I've got the ISO files on both a DVD and on an external drive. I may soon have a set of ISO files with the .wim file on an external drive. Is this suggestion just a performance consideration, or does DISM have an issue with accessing source on external drives?
