Hello everyone. I found this forum in the course of searching for an answer to the question I am about to ask. I found some other things on this forum related to my question, but none seemed to answer it exactly so I thought I'd give it a shot. I am trying to create an unattended Windows XP with SP1 installation disk, but I also want to separate the system files and the user data. To do this I make one 8GB partition for the system (C:) and a second partition taking up the rest of the space (D:). I have the unattended install working so that C:\Documents and Settings\ is instead located in D:, which is what I want. However, it would be ideal if I could have these partitions created and formatted before the installation process so it is truly "unattended." As it stands now, the point at which the install runs arbitrary commands is after the installation and if D: is not already formatted then the install halts. I've been looking into perhaps using BartPE and diskpart, but I am not sure how to go about doing that. All the documentation is very sparse, and what I want to do seems pretty simple. I've created similar scripts in the past to do this sort of thing for MacOS and Linux/UNIX, but is it possible with Windows? If so, can anyone here give me some advice about how to do it? Thank you.
