Solved Modify partition selection on work provided Win11 image without other changes

Hi all,
I have a Win11 image from my work and it's set to skip the partitioning and will choose a drive to install on automatically. I want to change it, either so that I can select the disk partitions interactively or to install on my second disk - but I don't want to change anything else about the installation as work provides many scripts etc that need to run.

Is this possible? It seems that it should be easy to edit the unattended configuration file but I've looked for unattended.xml on the usb and cannot find one.
Although I have found a ts.xml in \Deploy\Control\22H2\ and I can see a step for SMS_TaskSequence_Partition which looks promising. Is it enough to edit this ts.xml file and run the installer again?

I have attached setupact.log and ts.xml (as ts.txt) if it can help.

Many thanks

For a normal media-based install, you would skip the <DiskConfiguration> or <InstallTo> blocks in the unattended file.

Are you the WDS admin, or borrowing your company's image? The reason is if you don't have access to the WDS management server, then this exercise isn't going too far.

WDS modifies a provided ISO and injects hooks into the boot and install WIM's to run different task sequences. Those tasks reside on the WDS server, and the image is useless without the server providing the scripts.

"Format and Partition Disk (UEFI)" runs "%SCRIPTROOT%\ZTIDiskpart.wsf" to partition the disk.
"Set OSDisk" runs "%SCRIPTROOT%\ZTISetVariable.wsf"
"Install Operating System" runs "%SCRIPTROOT%\LTIApply.wsf", which presumably takes the Set OSDisk result as the disk number.

I am not WDS admin, so I guess this isn't going far.

Thanks for the reply, saves me banging my head on this deadend.

What exactly are you trying to achieve?

My primary m2/SSD is showing alerts that it may fail soon, so I got a replacement drive. The primary slot is behind the keyboard so I installed the replacement in the secondary drive slot since it was easily accessible. However when I do fresh install using the company provided ISO, it doesn't ask where to install and just picks drive0.

The obvious solution is that I need to take apart the laptop more to remove the failing drive and replace it. I was only trying to avoid taking the laptop apart more than I needed and from a quick search it seemed like it could be possible to either put the disk partition section back to interactive or at least set the install location to drive1.

If it’s your company laptop, why aren’t fixing/replacing the dying SSD?

Companies that use WDS or other deployment solutions will have a standardized HW config.

They normally insist on the system drive being in a specific slot, so the storage controller always picks the same device. This doesn't allow for much variation, and they wouldn't support design changes unless it's a new blessed config.

Sounds like everyone's waiting for the original SSD to fail, which might be soon but hasn't happened yet. As long as the work files are backed up and recoverable, you just wait it out or swap SSD's now.
