Creating a partition during unattended setup

[gospeed]

I currently have a working unattended DVD working but it is set to auto partition the drive as one. What I need is to be able to partition the drive into a c:/ and a d:/, with the install still going to the c:/ drive. The d:/ drive will always be 20gb, where the c:/ will be the remainder. I know I can do this manually, but is there any way to do this unattended? I want to use the d:/ as a recovery area

Thank you in advance! I have learned so much here at MSFN

This post point to a solution using WinPE or BartPE and diskpart scriptable utility:
