How To Fix the Bad System Config Info Error

Thankfully, there is no need to worry about the Bad System Config Info error since it's easy to fix. Need help with a particular issue? Here are five fixes for this troublesome error.

1. Restart Your Computer

The most obvious solution to your troubles is often the best: restarting your computer. By powering it off and then back on, you will resolve a variety of problems. Before moving onto more complex solutions, try rebooting your system first; it may be all that's needed to fix the Bad System Config Info error!

2. Run the System File Checker

The SFC scan is a command line tool that scans your system for corrupt or missing files and tries to repair them. This can be a great way of resolving the Bad System Config Info error if the cause is damaged system files.

  1. Reboot your computer and hold the F8 key on your keyboard while the boot screen is visible to enter the Windows Recovery Environment (WinRE). On certain devices, you may need to hold down the Fn (function) key as well.
    • Tip: If you can’t boot into WinRE using the keyboard shortcut, keep turning your computer on and off until it automatically starts in the repair environment. On average, you need to turn the computer on and off about 3 times.
  2. Navigate to Troubleshoot > Advanced Options > Command Prompt.
    Command prompt
  3. When the Command Prompt interface shows on the screen, input the following command and press the Enter key on your keyboard: sfc /scannow
    sfc /scannow
  4. After you execute the command, wait for it to finish checking your PC. Upon completion, close the Command Prompt window and restart your device to see if the Bad System Config Info error has been resolved.

3. Run the CHKDSK Command

Another command line program you can use to fix the Bad System Config Info error is CHKDSK. This utility scans your hard drive for errors, and it can be a great way of resolving this issue if disk corruption is to blame.

  1. Enter WinRE, and then navigate to Troubleshoot > Advanced Options > Command Prompt.
  2. When the Command Prompt interface shows on the screen, input the following command and press the Enter key on your keyboard: chkdsk C: /r
  3. Wait for the scan to complete.

If the CHKDSK scan finds any errors, it will attempt to repair them. After the scan is complete, restart your computer, and see if the Bad System Config Info BSOD error has been fixed.

4. Run the DISM Scan

The Disk Image Servicing and Management tool (DISM) is a powerful command line utility that can repair corrupted system files. Running a DISM scan might just solve the Bad System Config Info error if it's caused by damaged system files.

  1. Enter WinRE, and then navigate to Troubleshoot > Advanced Options > Command Prompt.
  2. When the Command Prompt interface shows on the screen, input the following command and press the Enter key on your keyboard: DISM.exe /Online /Cleanup-image /Restorehealth
  3. Wait for the scan to complete.

After you execute the command, wait for the process to finish. Upon completion, close the Command Prompt window and restart your device to see if the Bad System Config Info error code has been fixed.

5. Restore Your Registry

Because the Bad System Config Info error is tied to the Windows Registry, restoring it will help you resolve the issue. This method should always be performed exactly as our instructions say, as it involves editing the registry, which can cause more problems if done incorrectly.

  1. Enter WinRE, and then navigate to Troubleshoot > Advanced Options > Command Prompt.
  2. Input the following command, and then press Enter to execute it: dir D:\Win*
  3. You can tell you are in the correct drive by calling out a directory list from the Command Prompt. Next, execute these commands in the following order:
    • cd d:\windows\system32\config
    • xcopy *.* C:\RegBack\
    • cd RegBack
    • dir
  4. Carefully inspect the dates of all files located in RegBack directory. If any file is dated before the BSOD problem started, execute the following commands:
    • copy /y software ..
    • copy /y system ..
    • copy /y sam ..

Ensure that all of the commands are typed in exactly as shown in this article, with each symbol included! After executing all of the commands above, check if you can restart your computer without the Bad System Config Info error code appearing again.

6. Use Startup Repair

Another step in fixing a "Bad System Config Info" BSOD is to use the Windows Recovery Environment. This will allow you to boot into a special mode called "Startup Repair" which can help you recover from a number of different issues.

  1. Enter WinRE.
  2. Navigate to Troubleshooting > Advanced options > Startup Repair. This tool is going to check for issues with startup and attempt to fix your computer automatically.
    Windows startup repair
  3. Allow the repair to run and restart your computer. When it’s done, you’ll see if the Bad System Config Info stop code still comes up.

7. Use a System Restore Point

Windows comes with a built-in feature called System Restore. This feature allows you to roll back your system to a previous state and can be used to undo any changes that might have caused the BSOD error.

Warning: You may lose some newly installed applications! Make sure to check what programs and drivers will be affected during the System Restore process before you proceed.

  1. Enter WinRE, and then navigate to Troubleshooting > Advanced options > System Restore. If you have more than one Windows system on your device, select the one you want to restore.
    Windows restore
  2. Click Next, and then select one of the available restore points you wish to recover. After choosing one, click Next again.
    Windows restore
  3. Review the information about your restore point and confirm that your system was working properly at the time. After double-checking, click Finish and allow your device to make the necessary changes.

After using System Restore, your computer should reboot itself and operate using the configuration from an earlier date. See if this solves the error at hand.

Conclusion

By following the steps above, you should be able to successfully fix the "Bad System Config Info" BSOD in Windows and get your computer back up and running normally. If you're still having trouble after trying these steps, contact an IT professional for assistance. Good luck!
