automount (is it enabled)?
automount enable
exit
now reboot. Problem solved?
Issue: 3:
“The boot configuration data store could not be opened. The system cannot find the file specified.”
Symptoms
When you run Bcdedit /enum all you get the following error
“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
If we check under HKLM you will not find the key 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.
After Online Volume command, after reboot, label and ntfs is missing again and bcdedit doen't work.
If I assign "System Reserved" a letter and reboot, then it works fine but I know it never had an assinged letter, lol
Automount is disabled, should I enable and reboot?
System Reserved should never have a letter. It is not issued one during install. I've never heard of it going offline for any reason unless you're referring to manually editing the BCD.
Will this be another thread that goes on for three pages with bcd trivia but no resolution? Should I check back in a few days? Are these quicker solutions than the automated Repairs which we've used since release?
Please answer the question: What does deleting System Reserved and running a Startup Repair do?
