I have an issue with my unattended setup. I've gotten almost everything to work except for the fact that I'm installing this on preexisting systems that already have partitions. I have not found a way yet to get the unattended setup to simply blow away an entire disk and reimage it. I have tried setting the disk and create partition to delete, modify, and add, but it never seems to delete the partitions on the disk. Has anyone run in to this? <?xml version="1.0" encoding="utf-8"?> <unattend xmlns="urn:schemas-microsoft-com:unattend"> <settings pass="oobeSystem"> <component name="Microsoft-Windows-Shell-Setup" processorArchitecture="x86" publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS" xmlns:wcm="http://schemas.microsoft.com/WMIConfig/2002/State" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <AutoLogon> <Password> <Value>xxxxxxxxx</Value> <PlainText>false</PlainText> </Password> <Enabled>true</Enabled> <LogonCount>5</LogonCount> <Username>Administrator</Username> </AutoLogon> <OOBE> <HideEULAPage>true</HideEULAPage> <ProtectYourPC>3</ProtectYourPC> <SkipMachineOOBE>true</SkipMachineOOBE> <SkipUserOOBE>true</SkipUserOOBE> </OOBE> </component> </settings> <settings pass="windowsPE"> <component name="Microsoft-Windows-Setup" processorArchitecture="x86" publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS" xmlns:wcm="http://schemas.microsoft.com/WMIConfig/2002/State" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <DiskConfiguration> <Disk wcm:action="modify"> <CreatePartitions> <CreatePartition wcm:action="modify"> <Extend>true</Extend> <Order>1</Order> <Type>Primary</Type> </CreatePartition> </CreatePartitions> <ModifyPartitions> <ModifyPartition wcm:action="add"> <Extend>true</Extend> <Active>true</Active> <Format>NTFS</Format> <Label>OS_INSTALL</Label> <Letter>C</Letter> <Order>1</Order> <PartitionID>1</PartitionID> </ModifyPartition> </ModifyPartitions> <DiskID>0</DiskID> <WillWipeDisk>true</WillWipeDisk> </Disk> <WillShowUI>OnError</WillShowUI> </DiskConfiguration> <ImageInstall> <OSImage> <InstallTo> <DiskID>0</DiskID> <PartitionID>1</PartitionID> </InstallTo> <InstallToAvailablePartition>false</InstallToAvailablePartition> <WillShowUI>OnError</WillShowUI> </OSImage> </ImageInstall> <UserData> <ProductKey> <Key>XXXXXXXXXXXXX</Key> <WillShowUI>OnError</WillShowUI> </ProductKey> <AcceptEula>true</AcceptEula> </UserData> </component> <component name="Microsoft-Windows-International-Core-WinPE" processorArchitecture="x86" publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS" xmlns:wcm="http://schemas.microsoft.com/WMIConfig/2002/State" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <SetupUILanguage> <UILanguage>en-US</UILanguage> </SetupUILanguage> <InputLocale>0409:00000409</InputLocale> <SystemLocale>en-US</SystemLocale> <UILanguage>en-US</UILanguage> <UserLocale>en-US</UserLocale> </component> </settings> <cpi:offlineImage cpi:source="wim:c:/install.wim#Windows Vista ENTERPRISE" xmlns:cpi="urn:schemas-microsoft-com:cpi" /> </unattend>
