Hello,
This issue started last year when we updated to R2. the OS installed on anything but the C: drive. (that was fixed), however the Bitlocker partition BDEDrive keep getting a driver letter (S or D or E).
I was able to remove it with a diskpart.exe /s Diskpart.txt that remove the letter. Out of the blue that stopped working and now I see the letter on the partition again.
I have tried method 3 in this URL with no success : https://blogs.technet.microsoft.com/system_center_configuration_manager_operating_system_deployment_support_blog/2014/04/28/how-to-ensure-that-windows-installs-on-c-during-a-system-center-2012-configuration-manager-osd-task-sequence/
I do have the Do not assign a drive letter to this partition checked for the BDEdrive. How can I remove the drive letter during the TS? Thanks in advance
