[Bug]: Make2023BootableMedia.ps1 has errors

[jimgwhit]

Is there an existing issue for this?

• I have searched existing issues #347

Current Behavior

To get it to work, I extracred older ISO to a folder then mounted wim:

    Copied c:\windows\boot to location in mounted wim file same location
    Copied etfsboot.com from Windows kits folder to \boot folder
    Committed changes
    Ran the folowing:

    Make2023BootableMedia.ps1 -MediaPath C:\Media -TargetType ISO -ISOPath C:\Media\ISO\Win11_Updated.iso

And it worked. Note, the above was after applying the msu update. After applying the msu update I was still getting errors, but copying over the \Windows\boot folder wasn't enough, the Make2023BootableMedia.ps1 still had a missing etfsboot.com error. After I copied it over all worked great. I still don't understand why the msu update alone didn't work, but at least I have a way to make it work.

Expected Behavior

Updating the latest msu should be enough for the script to work

Steps To Reproduce

On windows 11 pro 25h2 and running the script errors still with missing files.

Build Environment

No build, just running script on a media folder errors.

Just FYI I even updated the latest ADK with the patches and a June 2024 cumulative which is after the april update.
It was windows11.0-kb5043080-x64_953449672073f8fb99badb4cc6d5d7849b9c83e8.msu

But I still got the error:

-MediaPath [media] does not have required binaries.
Make sure all required updates (2024-4B or later) have been applied.

The only way I have got it to work is the way I show here:

To recap that:

I got it to work, I extracred older ISO to a folder then mounted wim:

Copied c:\windows\boot to location in mounted wim file same location
Copied etfsboot.com from Windows kits folder to \boot folder
Committed changes
Ran the folowing:

@jimgwhit - to clarify, the target media to be updated is from the ADK (i.e WinPE)? This script is intended for full OS media and will not work cleanly on ADK/WinPE media. Note that the latest Windows 11 ADK has updated support to create WinPE images that are 2023 PCA compatible. New "bootex" flags were added to the relevant ADK scripts. Unfortunately, this doesn't help patch up older
WinPE media.
