I’m attempting to create a copy of the C:\ drive in Windows, but Disk Management is showing an error:

Disk Management

The boot configuration data of the system could not be updated.
Use bcdedit.exe to update it manually. Note that bcdedit.exe is not
available on Windows 2003 Server. Edit boot.ini or use
bootcfg.exe instead.


It’s clear that we won’t be using bcdedit.exe to modify the boot configuration data.

What steps can I take to ensure that Windows Disk Management functions properly and completes the required task?

Microsoft Windows [Version 10.0.18362.449]

The main issue under consideration is not how to create a mirror, as it has already been successfully created (as shown in the screenshot). Both disks in the mirror pair are Dynamic Disks, by the way.

The actual questions are:

– What is causing Disk Management to fail at updating the boot configuration data on a fresh installation of Windows 10 Professional?
– What measures can be taken to ensure that Disk Management is capable of updating the boot configuration data?

The reason for these inquiries is that if the primary disk fails and someone tries to boot from the mirrored disk, the boot sequence will fail. In previous versions of Windows (Windows 1000, Windows XP, Windows Vista, Windows 7, Windows 8, Windows 8.1, and pre-this version of Windows 10), using mirroring to duplicate a boot disk has worked fine.

What steps can be taken to rectify this issue?
