“The boot configuration data store could not be opened. The system cannot find the file specified.” 


Look for the following registry key HKEY_LOCAL_MACHINE\BCD00000000

Cause

If some 3rd party storage Disk or Storage Management software is installed it may bring all the volume without drive letter offline 

Generally 100 MB partition is system partition which contains Boot configuration Database and does not have a drive letter assigned.



Resolution

From command prompt

C:\>Diskpart

C:\Diskpart> List volume

C:\Diskpart> Select volume 1 (Considering this is 100 MB system partition)

c:\Diskpart> Online volume

C:\Diskpart> exit

OR 

From the Disk Management console assign the drive letter to the 100MB partition it should bring the disk online.

To access Disk Management, open command prompt 

C:\>Diskmgmt.msc

Select the 100 MB volume; Right click on the volume Change drive letter & Path; Assign a drive letter.

Assigning the drive letter will ensure the volume is not offline again after a reboot.


The volumes may go offline if AUTOMOUNT is disabled either while using a 3rd party storage software or if the user manually disabled the AUTOMOUNT for the volume. To check this type the following command after running diskpart in the administrator command prompt 

DISKPART> automount

Automatic mounting of new volumes is disabled.

To enable AUTOMOUNT run the following command

DISKPART> automount enable

Reboot the server and the volume will not go offline.
