Creating a basic unattended is easy.

I need to add two things to my unattended though.

1) How do I automatically create user accounts using unattended installations?

2) How do I automatically partition my hard drive using unattended installation?
-Primary 7GB
-Extended
--Logical, rest of the HD

The file you want is nLite - nLite - Deployment Tool for the bootable Unattended Windows installation (http://www.nliteos.com/)

This simplifies everything for you...
