I notice that the autounattend.xml created by Se7en_UA (I'm using 6.1.0) is always missing the DiskID element, for example: <DiskConfiguration> <WillShowUI>Never</WillShowUI> <Disk wcm:action="add"> <DiskID>0</DiskID> <!-- This element is always missing and causes a parse error during setup --> <WillWipeDisk>true</WillWipeDisk> <CreatePartitions> <CreatePartition wcm:action="add"> <Order>1</Order> <Type>Primary</Type> <Extend>true</Extend> </CreatePartition> </CreatePartitions> ... If I add the DiskID manually, install works. A question: After I do everything, including inserting hotfixes into the WIM and then packing the image, is there a way to roll back to change settings, add more hotfixes and apps etc? Or do I have to start from copying from my Win7 install DVD?
