I am trying to use our autounattend.xml to install Windows 7 SP1 64bit onto a Latitude E6520. This autounattend works fine for all of our 64bit machines except for these new 6520's. It's giving an error as it goes to copy files: "Windows could not set a partition as active on disk 0. The target disk, partition, or volume does not support the specified operation. The error occurred while trying to apply the unattend answer file's <DiskConfiguration> setting. Error code: 0x80300024 . When not using the autounattend file Windows installs without a hitch.
As said, this unattend works with other machines. It has this issue whether we use AHCI or IRRT, but only when using the unattend. Here is a copy of my DiskConfiguration:
<DiskConfiguration>
<Disk wcm:action="add">
<CreatePartitions>
<CreatePartition wcm:action="add">
<Order>1</Order>
<Size>200</Size>

<CreatePartition wcm:action="add">

</CreatePartition>
</CreatePartitions>
