This error apparently occurs as a result of encrypting with BitLocker and the partition made for it has become corrupt in some way (or is missing).
apparently the 'S' is a giveaway.
Not sure how to resolve, however this may help.

To check the Registry location for the offending file you can use Msconfig
Click Start and type msconfig and press Enter.
For the first suspicious item, expand the "Location" column to see where it is loading from in the registry.
Click on Start, Run, type "regedt32" and click OK.
Browse to the key listed in the "Location" column for Msconfig.
Delete the key on the right hand side only, that specifically matches that startup item. **See example below.**

Note the "Command" folder in Msconfig. Browse to this folder, and delete the .exe file itself. **See example below.**

:::::EXAMPLE:::::
In this example, the Startup Tab of Msconfig indicates that:
xyz.exe loads from Command "C:\WINDOWS\xyz.exe" and Location

"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run"
In this case, we go to the registry editor and find that Run key on the left window. On the right hand Window pane you'll see each item in that Run key, specifically "xyz.exe" in this case. Delete the entry for "xyz.exe" in the registry only.
In addition, we'll browse to the C:\WINDOWS folder, and manually delete the xyz.exe file that resides there if it is still there.
Repeat these steps for each suspicious item.

Keep us informed as to your progress if you require further assistance.
