"Autopartition" flag in WINNT.SIF not working

[Pan_]

The title says it all.

I'm trying to make a fully unattended/automated setup, thus, I do not want the "select partition" screen. In my WINNT.SIF file, I set "Autopartition" to 1. Here's a snippet:

[Data]
AutomaticUpdates="No"
Autopartition=1
MsDosInitiated=0
UnattendedInstall="Yes"

As you can see, Autopartition equals 1. I've heard somewhere that you also need to set "Repartition" to 1, but I also do not want to erase the entire disk. Any help would be appreciated.

Thank you!!!
