mkesler80 Posted December 10, 2015 Report post Posted December 10, 2015 (edited) I have a task sequence that was working prior to updating to 2012 R2 SP1 and was working post SP1 until I changed boot images. From 8.1 ADK 6.3.9600.16384 to Windows 10 ADK 10.0.10586.0. Now, after applying the OS image(Win 7 Ent x64 Sp1), pre-provisioning Bitlocker, and rebooting winload.exe throws an error, 0xc0210000, and says it cannot decrypt the drive. I made sure that the correct partition is getting encrypted. It's set to the OSDisk variable which is the C: drive of the OS image. I've tried using both the new and old boot images. Both show the same behavior. The task sequence doesn't report a failure just that the OSD is still in progress. What do I do? Disabling pre-provision and just enabling bitlocker later would add too much time to my image deployment. Edit - Tried creating a new Task Sequence and it is showing the same behavior. Here's a screenshot of the task sequence in case there is some step I'm missing. I went ahead and disabled bitlocker pre-provisioning and enabling, just so my helpdesk can move forward with imaging. It's most a standard MDT task sequence. Edited December 10, 2015 by mkesler80 Quote Share this post Link to post Share on other sites More sharing options...
pembertj Posted December 16, 2015 Report post Posted December 16, 2015 I started running into this as well... looks like this is the issue... but haven't found a good fix yet short of disabling pre-provisioning like you did... **Windows 10 1511 (build 10586) includes a new bitlocker encryption, XTS-AES encryption algorithm, which cannot be read by earlier versions of Windows.. so that is most likely the reason.** https://social.technet.microsoft.com/Forums/en-US/07c809fc-486b-49aa-8df8-70e374d90402/sccm-2012-r2-sp1-preprovision-bitlocker-windows-7-cannot-read-drive-after-reboot?forum=configmanagerosd Quote Share this post Link to post Share on other sites More sharing options...
