    Hi!

    How exactly did you perform the copy? Did you use commands or a standard Windows copy operation?

    Did you change any folder permissions in Windows?

    Is the hard drive connected via a SATA cable or USB?

    Did you eject and disconnect the hard drive after performing the backup?

    BAD_SYSTEM_CONFIG_INFO usually means the SYSTEM registry hive is corrupted or missing required registry keys or values.

    Try these steps in order:

    1. Check free disk space Low free space can prevent Windows from working normally. A good target is to keep at least 10% to 15% free space on the system drive.
    2. Try Safe Mode, then restart normally If Windows can enter Safe Mode, restart normally afterward. If that does not fix it, the registry damage is likely more extensive.
    3. Use System Restore In Windows Recovery Environment, go to Troubleshoot > Advanced options > System Restore and restore to a point from before the problem started.
    4. Run DISM, then SFC Open an elevated Command Prompt and run: 
         DISM.exe /Online /Cleanup-image /Restorehealth
   sfc /scannow
      Important:
      • Run DISM first, then SFC.
      • Do not close the Command Prompt while sfc /scannow is still running.
      • If SFC says it could not perform the requested operation, run it in Safe Mode.
    5. Check Event Viewer if Windows becomes bootable Look in the System log for registry-related errors that identify a specific hive or key.
    6. If recovery still fails, use Windows recovery options Try these in order:
      • Reset this PC
      • Use installation media to restore or reset the PC
      • Reinstall Windows
    7. If the old HDD is failing, suspect hardware Intermittent disk detection or repeated boot corruption can indicate an underlying HDD/SSD problem. Replacing the failing drive and reinstalling or cloning to a healthy disk may be necessary.
