The Boot Configuration Data for your PC is missing or contains errors

I came home one day and got a blue screen when trying to start up my computer. The error said "a required device isn't connected". I tried solving this problems in a lot of ways but I think I only made things worse cause now the error says

"Your PC/Device needs to be repaired

The Boot Configuration Data for your PC is missing or contains errors.

File: \Boot\BCD

Error code: 0x000000f

You’ll need to use recovery tools. If you don’t have any installation media, contact your PC administrator or PC/Device Manufacturer."

I've read through countless peoples posts about the same problem and different possible solutions but haven't found anything to solve my problem.

I’ve booted from a recovery drive, selected ‘Repair your computer’ and tried to rebuild the MBR and BCD via the Command Prompt Option. I’ve run the following commands:

bootrec /fixmbdr
The operation completed successfully.

bootrec /scanos
Successfully scanned Windows installations.
Total identified Windows installations: 0
The operation completed successfully.

bootrec /rebuildbcd
Successfully scanned Windows installations.
Total identified Windows installations: 0
The operation completed successfully.

bcdedit /export c:\bcdbackup
The store export operation has failed.
The system cannot find the file specified.

I've tried using Kyhi's recovery tools (Windows 10 Recovery Tools - Bootable Rescue Disk - Windows 10 Forums) but I'm not sure what to do with it to fix my problem. When I try to use easyBCD I can't locate the BCD Registry that is supposed to be in the Boot folder.


In MiniTool Partition Wizard it seems to me like everything is fine.


Basically I have Kyhi's recovery tools but I don't know what to do with them. My hope is that anyone of you can tell me what to do.

Please help me. Thank you.

Thank you for your answer.

I believe I've tried that with no avail but I will try it again when I get home to make sure and post the results here.

Thank you, I'll make sure to try that as soon as I get home.

I followed your instructions but Macrium could not find an operating system. See image below.


I pressed next anyway and selected C: and pressed next again.



I ran the fix and everything seems to have worked fine. I then restarted my computer.



I was greeted with a new error



Any idea on what to do next?



To dalchina.

Here's the result from the HD Tune Health tab.



I am currently doing an error scan with no damaged blocks after 15 minutes. I will leave it on and come back later and post the result.



To bro67.

Thank you for your suggestion. I will try it after the error scan is completed and post the results.



So to summarize I currently have this error when trying to boot my computer.

Windows could not start because the following file is missing or corrupt:
<Windows root>\system 32\hal.dll.

About the "hal.dll" error:

First remove the external USB stick (Win 10 PE) from your PC's USB connections - then try to reboot your PC one time more!

Thank you both, I will try what you've said tomorrow.
