Since no one replied let me ask the question again. Can someone tell if it is possible to perform mountvol/diskpart during windows xp setup and then use the mounted partition for special folders such as program files and documents and settings? Final windows xp installation should look like this C:/Windows on partition 1 C:/Program Files on partition 2 (mounted as folder c:/program files during unattended install) C:/Documents and settings on partition 3 (mounted as folder c:/D & S during unattended install)
