Dear Export, I'm using Win2k3 unattended installation to change the profile directory to another partition (I use C for normal system files and D for profiles). Yes, I know how to do it in winnt.sif. But my problem is I use a new HDD, and I partition it into two partitions. The Windows installer only lets me do partitioning; there's no way to format ALL the partitions before I install it. Therefore, if I instruct the installer to place the profile directory in to D (the second partition), and because I cannot format D, the installer will report an error and cannot continue. Is there any way to achieve this? Thanks in advance! Lei
