Fix Bad System Config Info Error in Windows

Many reasons can cause the Bad System Config Info stop code error. Here is how to fix the Bad System Config Info error in Windows.

The “Bad System Config Info” is one of the most common stop code errors for many Windows users. When it happens, you will see a BSoD (Blue Screen of Death) screen with little to no information why the error occurred.

When the Bad System Config Info error happens, the system either shows the BSoD screen or goes into a boot loop. If it goes into a boot loop, you will be unable to log into your computer to troubleshoot or fix the prompt.

Reasons for Bad System Config Info error

There are several reasons why the error is so common among Windows users. Those reasons include but are not limited to a bad boot configuration file, failed Windows updates, problems with drivers, registry errors, etc.

No matter the reason, if you are seeing the Bad System Config Info error, it is relatively easy to fix. All you have to do is make sure the BCD file is intact, uninstall any problematic updates, update drivers, or scan to fix registry errors.

Though it sounds a lot, it is pretty easy to troubleshoot and fix the Bad System Config Info problem.

So, without further ado, let me show you how to fix the Bad System Config Info error in Windows operating system.

Use the System Restore

System Restore is one of the best and easiest ways to fix Windows problems.

When installing a driver or Windows update, the system will automatically create a new restore point if the System Restore functionality is turned on.

When something goes wrong, you can fire up the system restore tool, select an appropriate restore point, and restore the system to that specific point in time. Windows will roll back the driver updates, applications, and Windows updates on restore. System Restore will not touch personal files. That way, most problems are fixed automatically. The same applies to fixing the Bad System Config Info error.

Here is how to restore the system to fix the Bad System Config Info BSoD error.

  1. Open Run with “Win + X” shortcut.
  2. Type “rstrui.exe” in the blank field.
  3. Click the “Ok” button.
  4. Click “Next.”
  5. Select the restore point from the list.
  6. Click “Next.”
  7. Press “Close” in the affected programs window.
  8. Click the “Finish” button.
  9. System reboots automatically to restore it.
  10. After reboot, the Bad System Config Info is fixed.

Same steps with a bit more detail and screenshots:

You need to open the System Restore tool. You can do that in multiple ways. One of the easiest ways is via the Run command. So, open the Run dialog box with the “Windows key + R” shortcut, type “rstrui.exe” in the field, and click the “Ok” button.

The above Run command will launch the System Restore tool. Click the “Next” button to proceed to the next screen.

Here, the tool will show all the available restore points. To see more, you can select the “Show more restore points” checkbox. Select the restore point of your choice. I recommend you choose the most recent one. Click the “Next” button to continue.

After logging in, you should no longer see the Bad System Config Info error.

Fix the BCD file

If the Boot Configuration Data file is the problem, fixing it will automatically fix the Bad System Config Info problem. The good thing is, you can follow this method even if you cannot boot into the system. Here is how.

  1. Boot into the Advanced Startup screen.
  2. Select “Troubleshoot.”
  3. Choose “Advanced Options.”
  4. Click on the “Command Prompt” option.
  5. Execute the below command one after another.
    bootrec /repairbcd
    bootrec /osscan
    bootrec /repairmbr
  6. Close the Command Prompt window.
  7. Reboot the computer.
  8. With that, the Bad System Config Info is fixed.

Uninstall recent Windows Update

Sometimes, an innocent-looking Windows Update might be the reason for the Bad System Config Info and many other system-breaking errors. So, whenever something is wrong with your system, uninstalling the most recent update should fix the issue. Here is how to do it.

  1. Launch the Settings app.
  2. Go to the “Windows Update” page.
  3. Click on the “Update History” option.
  4. Scroll down and click on “Uninstall updates.”
  5. Select the most recent update from the list.
  6. Right-click on the update you want to uninstall.
  7. Select the “Uninstall” option.
  8. Click “Yes” or “Ok” to confirm the action.
  9. After uninstalling, reboot the computer.
  10. With that, the Bad System Config Info should be fixed.

Reinstall or Update drivers

If you recently installed a driver or if the driver is outdated or incompatible, it might be the culprit in causing the Bad System Config Info error. In that case, reinstalling or updating the drive will fix the box. Here is how to do it.

  1. Right-click on the Start menu.
  2. Select “Device Manager.”
  3. Click the “Action > Scan for hardware changes” button.
  4. See if any hardware icon has a yellow exclamation mark.
  5. If you find it, right-click on it.
  6. Select the “Update driver” button.
  7. To reinstall, select the “Uninstall device” button.
  8. Click “Yes” or “Ok” when prompted.
  9. Close the Device Manager.
  10. Reboot the computer.

After updating or rebooting the computer, the error should be fixed. If you are trying to reinstall or update the graphics driver, I recommend downloading the latest driver from the manufacturer’s website.

Check your hard drive & memory

Sometimes, it might be a hardware issue causing the bad config error in Windows. Mainly, you need to look at the hard drive and memory (RAM).

For example, if the RAM or hard drive is not seated correctly or damaged somehow, it can cause all kinds of errors, including the Bad System Config Info error.

If you can, shut down the computer, detach both the hard drive and memory, and plug them in again. After that, reboot the computer. If the problem is related to hardware, it should be fixed.

If possible, I recommend plugging in the detached hard drive and RAM to another computer and see if you can replicate the problem. Suppose you can then one of those devices is damaged. You have to replace them to fix the issue.

Fix the Registry

Often, corrupted or mismatched registry values can cause many different errors in Windows. One such error is the Bad System Config Info stop code. In that case, fixing the Registry will fix the problem.

First, we need to boot into the Advanced Startup screen. You can do that in multiple ways, depending on whether you can boot into Windows or not. So, follow the linked guide to learn how to boot into the Advanced Startup screen.

Go to the “Troubleshoot > Advanced Options” page in the Advanced Startup screen. Here, click on the “Command Prompt” option to open it.

In the Command Prompt window, execute the below commands one after another.

cd C:\Windows\System32\config
ren C:\Windows\System32\config\DEFAULT DEFAULT.old
ren C:\Windows\System32\config\SAM SAM.old
ren C:\Windows\System32\config\SECURITY SECURITY.old
ren C:\Windows\System32\config\SOFTWARE SOFTWARE.old
ren C:\Windows\System32\config\SYSTEM SYSTEM.old

After that, execute the below commands one after the other.

copy C:\Windows\System32\config\RegBackDEFAULT C:\Windows\System32\config\
copy C:\Windows\System32\config\RegBackSAM C:\Windows\System32\config\
copy C:\Windows\System32\config\RegBackSECURITY C:\Windows\System32\config\
copy C:\Windows\System32\config\RegBackSYSTEM C:\Windows\System32\config\
copy C:\Windows\System32\config\RegBackSOFTWARE C:\Windows\System32\config\

Once done, close the Command Prompt window and reboot the system.

If the Registry is the culprit, the above actions should fix the Bad System Config Info problem.

Reset the computer

If everything else fails, you can reset Windows. Resetting is much like reinstalling the OS but with much less work. Of course, you have to re-install all the applications and configure Windows settings after resetting.

So, if possible, back up the application data and reset the computer. I’ve already written a detailed guide on how to reset Windows 11; it also works for Windows 10. Follow.

It is that simple to fix the Bad System Config Info error in Windows 10 and 11.

I hope this simple and easy Windows 11 guide helped you.
