Windows 10: Problem with Win11 24H2 using autounattend.xml

I have been stuck for days trying to make an answer file work with Win11 24H2 installation.I have created the answer file using the Windows System Image Manager and the media I am using for the installation.Initially I tested with a prepped image and it would just fail with error "Windows 11 Installation Failed" past 55%. I stripped the answer file from most settings keeping only the minimum settings that are mandatory for my automatic installation. Now I have tried with \autounattend.xml and the installation doesn't fail but it seems to skip entirely the specialize and oobeSystem passes as I

Windows 10 autounattend xml installation problem

Hi guys, I have a problem with autounattend XML install. Basically, I have a Windows image that is downloaded from MS and edited to skip all steps for setup. The windows boots and wipe the hard drive created partitions, select language, and created one admin account with the password. The image work when I test it on a laptop and everything seems fine. The image is not working on Virtual box or Hyper- V, when it's, starts on the parts that create partitions I received that error:
windows could not create a partition on disk 0 the error occurred while applaying the auto unnatednd asnwer file's < DiskConffiguration>Setting. Error code: 0x80042565 . The main issue is that I set up a TFTP server and crated WinPE to boot from the samba server where the image is so that I can boot it from the network. When I tested the image from the server it's finding the image and start the setup but I receive the same error with the creation of the partitions like on a virtual machine. With a flash drive, it works I don't know what might be the problem if someone has an idea?

Ok, that's a good start.

Your answer file is made for a Gen 2 Hyper-V. It won't work on Gen 1.

Verify the settings I have outlined in the image below:





NOTE: I have not looked at the answer file in detail. If you are still having difficulty, I'll look closer, but for now, time for sleep. It's 0500 here *Smile

Hyper V gen2 configurations are like yours but when I start the VM I get that error:


I have done one more thing to the image, I loaded the image with NTLITE and there is an option explore mount directory basically there you can add a folder with files so when the image is installed for example you can have it in C:\CustomFolder with files and after that, with the program, you created the ISO file.
