For several reasons I need to be able to customize MDT, so that I can choose which partition I want to install Windows on. We already have this option when we install from a simple Windows DVD, so why is it so hard to implement this into MDT?
Any suggestions on how I can proceed?
You can select what partition/disk you apply Windows to by going to the task sequence and selecting your install operating system task.
After you select it you will notice that there is a section (under the "Operating system to install:" selection box) that allows you to define where the OS will be installed to.
My installation automatically collects the drive letter from the disk format stage and apples to the primary disk automatically (to whatever drive letter the primary disk is mounted to).
Hope this helps!
