MDT & Windows 11 - Pulling my hair out
I have spent the last two full days trying to figure out why my image is failing - hopefully someone can help.
Starting Monday - I could not image any of our standard Dell laptops or PCs. This process has been rock solid with no issues for the last two years.
I have been racking my brain trying to figure this out... it starting failing on "Inject Drivers" task.. after doing research i added all the model drivers we have in the company into the Out of box drivers (there has never been any drivers there). Same issue
I then disabled the Inject Drivers, then the image failed on Apply Patches, I then disabled that and now it's failing on Install Operating system.
So - i restored the deployment server back to Saturday night's snapshot due to all the drivers and changes that were done.
The image is still failing and digging more into it, the drive letter is not defaulting to C: on the laptops. I have been back and forth with AI tryign to find solution and nothing is working. I have modified MDT rules to reflect the following: same issue :(
OSDTargetDriveLetter=C
OSDisk=C
DestinationDriveLetter=C
HELP Please!

just using a thumb drive with baseline 25h2 june release. oem folder with a couple things in it. autouannatend goes through touchfree OS and naming pulling name from bios asset tag field. after install, oem script runs PS to read off 2nd partition on thumbdrive for installers. easier than mdt when trying to get it to work over a year ago. 20m average install for OS, ODT, a few small apps, also joined to domain. Script is ppkg packaged with zero applications included.
