Okay so I am digging into windows AIK, I need to make sure it will format the drive (all drives have 2 partitions), then install.
Bonus question, anyone know where I can get some GMA 4500 CAB's?
Inside WAIK, under the section Microsoft-Windows-Setup\DiskConfiguration\Disk\ModifyPartitions\ModifyPartition
you need to set a few options
Format=%FILESYSTEM TYPE%
and PartitionID=%ID OF PARTITION TO FORMAT%
for both partitions.
