Hi, name is Brian. I'm new to the forums and i'm having trouble with the disk config portion. This is what I have currenty <DiskConfiguration> <WillShowUI>Never</WillShowUI> <Disk> <CreatePartitions> <CreatePartition> <Order>1</Order> <Type>Primary</Type> <Extend>true</Extend> </CreatePartition> </CreatePartitions> <DiskID>0</DiskID> <WillWipeDisk>true</WillWipeDisk> <ModifyPartitions> <ModifyPartition> <Active>true</Active> <Extend>False</Extend> <Format>NTFS</Format> <Label>SYSTEM</Label> <Letter>C</Letter> <PartitionID>1</PartitionID> <Order>1</Order> </ModifyPartition> </ModifyPartitions> </Disk> </DiskConfiguration> For some reason it is not wiping the disk and doesn't recreate the partition EDIT: Using RTM with the newest WAIK. Also tried using RC2 with the same issues.
