SYMPTOMS

Consider the following scenario:

You have a computer that is running Windows XP.
You attach a hard disk drive that contains a Windows 7-based or Windows Server 2008 R2-based system partition to the computer.
You try to run the BCDBoot.exe tool to repair the Boot Configuration Data (BCD) store in the system partition on the attached hard disk drive.

In this scenario, the repair operation may fail.

If you copy and then run the BCDBoot.exe tool on the computer that is running Windows XP, you receive an error message that resembles the following:

BFSVC: Failed to close the system store. Status = [c0000121]

If you run the BCDBoot.exe tool in the Windows 7-based or Windows Server 2008 R2-based system partition, you receive an error message that resembles the following:

BFSVC: BfspSetSecurityDescriptor(\\?\GLOBALROOT\Device\HarddiskVolume3\Boot<file:///\\%3f\GLOBALROOT\Device\HarddiskVolume3\Boot>) failed! Last Error = 0x7f

BFSVC: Error copying boot files from F:\Windows\boot\PCAT to \\?\GLOBALROOT\Device\HarddiskVolume3\Boot<file:///\\%3f\GLOBALROOT\Device\HarddiskVolume3\Boot>! Last Error = 0x7f Failure when attempting to copy boot files.

Windows 7 and Windows Server 2008 R2 file information notes

Important Windows 7 hotfixes and Windows Server 2008 R2 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems.
