Can not install Windows 8.1 to a Bitlocker Pre-Provisioned volume

Hello,
I'll come straight to the point. What I'm trying to do is to install Windows 8.1 Enterprise to a Pre-Provisioned volume but Windows does not let me do that. The steps I've performed are.
With Microsoft ADK I created me a WinPE media which has the components installed to get the manage-bde command working. I used the article hxxp://technet.microsoft.com/en-us/library/hh824926.aspx for that.
I prepared an USB stick with the manage-bde components on it and booted my test laptop with it.
Started diskpart and used commens in order to get a new clean partition:
Select Disk 0
clean
Create Partition Primary
Format fs=ntfs quick
Assign letter=c
exit
After that I pre-provisioned the volume with the command:
manage-bde -on -used c:
When I check with manage-bde -status it states that:
Conversion Status: Used Space Only encrypted
Percentage: 100
Protection Status: Protection Off
Lock Status: Unlocked
Identification Field: Unknown
Automatic Unlock: Disabled
Key Protectors: None Found
OK. After that I use the net use command to map a network share with the Windows 8.1 x64 Enterprise installation media itself. I execute setup.exe without any parameters.
I can navigate all the way through the dialog "Where do you want to install Windows?". I can see there now "Drive0Partition 1" with a Total size of 119.2 GB and almost as many free space BUT when I select it and click next there comes
only a warning dialog saying:
We couldn't not create a new partition or locate an existing one. For more information, see the Setup log files."
The best description of the problem I've found from the file x:\windows\panther\setupact.log where are lines like:
BLOCKING reason for disk 0 offset bla bla is either "The partition is too small" (????) or "Bitlocker Drive Encyption is enabled on the selected partition".
What I am missing here? Is there a special trick how to get Windows installed on a pre-provisioned drive? I also loaded the correct driver for the disk controller but no help. As soon as I clean the disk and create the partition new without pre-provisioning
I can install Windows without any problems.
Sorry for the long text. Hope someone of you has an idea.
Regards
Robert

Hi,
For this issue,when you assign letter,you need to mark a partition as active.
Using a command line
1.Open Command Prompt.
2.Type: diskpart
3.At the DISKPART prompt, type: list partition
Make note of the number of the partition that you want to mark as active.
4.At the DISKPART prompt, type: select partitionn
Select the partition, n, you want to mark as active.
5.At the DISKPART prompt, type:
active
Hope this helps.
