Issues using BitLocker in Windows 8 Emedded with 2012 SQL Server Express

Question

I was told that this forum may be able to help me with my issues (see original thread here:
https://social.msdn.microsoft.com/Forums/sqlserver/en-US/8c81fde1-e91b-46eb-8d2f-b79426805ddd/using-sql-server-2012-express-with-bitocker?forum=sqlexpress).
Background:
To summarize, I have an OS that is partitioned into two volumes: C and D.
C drive contains the running software, SQL Server install, and the OS.
D drive is the encrypted partition via BitLocker. The SQL Server files are stored here (logs, backup, and mdf).
Problem:
The software cannot connect to the database stored on the encrypted D volume when BitLocker is turned on. The user account that I use to enable BitLocker is the same SQL Server Service account and has is also part of the Local Admin Group. As soon as I disable
BitLocker, the software works fine and the database connection succeeds. I am currently using the SQL System Admin account to login (SA) and BitLocker is being used with a TPM.
The error I am experiencing when connecting through the software is 'login
failed for user sa'.
Thank you for the suggestions/help.

Hi HMLunger,
Did you install the SQL Server instance successfully? If not, please help to post the summary and detail logs for analysis. By default, the logs can be found in: C:\Program Files\Microsoft SQL Server\110\Setup Bootstrap\Log.
However, if you fail to start SQL Server Express service after successfully installing SQL Server,
you might have to change the paths of the files by running the following scripts from the command prompt. For more details, please review this similar
thread.
NET START MSSQL$SQLEXPRESS /f /T3608
SQLCMD -S .\SQLEXPRESS
ALTER DATABASE model MODIFY FILE (NAME = logical_name , FILENAME = 'new_path\os_file_name');
ALTER DATABASE model MODIFY FILE (NAME = logical_name , FILENAME = 'new_path\os_file_name');
go
exit;
ALTER DATABASE msdb MODIFY FILE (NAME = logical_name , FILENAME = 'new_path\os_file_name');
ALTER DATABASE msdb MODIFY FILE (NAME = logical_name , FILENAME = 'new_path\os_file_name');
NET STOP MSSQL$SQLEXPRESS
In addition, you can follow the steps in this KB article to uninstall SQL Server.
