MDT Media Missing - AnisKhan - 09-14-2021

Hello there.

When using Ventoy, I am having difficulty with Microsoft Deployment Toolkit (MDT).  During the application installation part (after a few reboots), it says the 'media is missing'.  It seems like there is a persistence issue.

Otherwise, Ventoy works really well during the initial part (menu, selecting and running the ISO etc).

Is anyone else having this issue or am I doing something wrong?

Thanks, Anis

On first reboot, the ISO on the USB drive is loaded as a virtual DVD drive so that Windows Setup can access the install files on the virtual DVD.
On all subsequent reboots, the ISO will not be loaded as a virtual DVD drive and so any install scripts which assume that the 'DVD' is present will not work.
If on 2nd and subsequent reboots you need access to files on the ISO, you need to load the ISO as a virtual DVD drive yourself before the rest of the MDT script starts.

Thank you Steve2926.

How would you 'load the ISO' without booting from it?  We need MDT/Windows to run normally via the hard drive but still access the virtual DVD drive.  Otherwise it would restart the whole MDT boot process.

Just had a thought, maybe load the vitual dvd drive via the Ventoy menu but at the point where is says 'press any button to continue' just let that time out?

Any suggestions would be appreciated (new to this).

Copy some script/exe to the local disk drive during the first boot install progress and make them start automatically.
On all subsequent reboots, load the ISO file as a virtual DVD drive with these script/exe ...
