I was playing around with Sysprep when I hit a weird issue with VirtualBox and Encrypted folders on the host.
unattended.xmlon the host, encrypted (with Windows EFS).
- Virtual Machine, hosted in VirtualBox
I mounted the folder with
unattended.xml (and other files) inside the VirtualBox and started sysprep (
sysprep+shutdown.cmd just executes the sysprep with the
unattended.xml from the location and copies a
When booting the VM I got the following error:
To investigate the error I hit up Shift+F10 and checked
c:\Windows\Panther\setuperr.log, which had the following error:
[setup.exe] UnattendSearchExplicitPath: Found unattend file at [C:\Windows\Panther\unattend.xml] but unable to deserialize it; status = 0×80070005, hrResult = 0×0.

By using the command
I saw this:
E, which means, Encrypted.
confirmed my suspicion:
After removing the file with a Windows disk BEFORE the first boot (afterwards it doesn’t work it seems) the boot went fine, I sysprepped it again (with a non-encrypted unattended.xml) and all went fine.
So make sure you don’t copy
unattended.xml to a machine that is encrypted. The keys are lost upon sysprepping!
