Bcdedit not available when booting via network (WDS

Hello,

I am trying to deploy an image of a windows 8 via a WDS . The system which is deployed runs uses UEFI Boot, after booting from the network I could deploy the image using Dism /apply-image /imagefile:Z:\SystemDisk.wim /index:1 /applyDir:C:\
I also deploy the content of the System partition S which is hidden.

When deploying this via Network the command bcdedit does not work, it complains

"The boot configuration data store could not be opened. The requested system device cannot be found.".

When I am doing the same using an USB Stick (using oscdimg -n -m -g -h -bC:\winpe\fwfiles\etfsboot.com c:\winpe\media c:\output.iso)it works well.

This what I try to do.

1. Install a 8 embedded on one PC using UEFI Boot
2. Creating at least 2 wim files (system(efi disk) Systemdisk aka C:\)
3. Create a wim file with script for the wds
4. Share the 2 wim files
5. Boot via network from the wds my custom wim from point 3
6. Use Diskpart clean the a disk and create new partitions
7. Deploy the wim files using dism
8. Edit BCD to set the correct disk (c:\)
9. Reboot

Doing this from a usb Stick works fine, trying the same from the WDS I could not open the data store bcdedit fails.

Does anybody have an idea what may be could causes this issue ?
