BSOD with REGISTRY ERROR Stop Code

Hello, everyone!

I was updating BIOS (to 1.58) on my ThinkPad T470 yesterday, it went fine and the system went into reboot. I'm not sure, but there might have been some Windows updated scheduled to be applied at reboot as well. The OS (Windows 10) couldn't load - BSOD with with Stop Code 'REGISTRY ERROR'.

The recovery options accessible via Windows Installation Media don't work. System Restore doesn't work.

bootrec.exe /rebuildbcd - returns the "Total identified Windows installations: 0" thing;

bootrec.exe /fixmbr - returns "The request could not be performed because of an I/O device error"

bootrec.exe /fixboot - returns "Access is denied"

chkdsk c: /r - returns "Windows cannot run disk checking on this volume because it is write protected"

Ran health diagnostics on the system SSD - all good.

Would appreciate some help. Thank you.

    Hi Alexander,

    Thank you for writing to Microsoft Community Forums.

    This error indicates that the registry encountered an I/O error while trying to read one of its files. This can be caused by hardware problems or file system corruption. It may also occur due to a failure in a refresh operation, which is used by the security system and when resource limits are encountered.

    You may want to restore the registry hives and see if the PC boots to the desktop.

    • Boot the PC into Windows Recovery Environment using the installation media and navigate to Troubleshoot > Advanced Options > Command Prompt
    • Copy paste the following command to navigate to the config directory: C:\Windows\System32\config

    (*Note: C:* is the drive where Windows is installed.)

    • Rename DEFAULT, SAM, SECURITY, SOFTWARE, SYSTEMto DEFAULT.old, SAM.old, SECURITY.old, SOFTWARE.old, SYSTEM.old respectively.
    • Now, copy the registry hives from C:\Windows\System32\config\RegBackto C:\Windows\System32\config.
    • Once the registry hives are copied, exit Command Promptand boot the machine to see if it works.

    Let us know how it goes.

    Regards,

    Hello Junaid,

    Thanks very much for your response.

    When I try to rename the files, I get this message: "T he media is write protected"

    Some additional info on the issue.

    This is what I get using Diskpart from the Windows Recovery Media:

    Current Read-only State: Yes

    The command

    DISKPART> attributes disk clear readonly

    returns

    DiskPart failed to clear disk attributes
