How to Fix “Bad System Config Info” Error in Windows

It’s not uncommon for Windows computers to get a bug check error known as “Bad System Config Info,” which is usually brought on by a problem with the operating system’s registry, the system’s boot configuration data file (BCD), or both.

There is a possibility of incompatibility between newer, more stable files and those in the boot sector of the BCD. The dreaded “Blue Screen of Death” (BSoD) error message will appear.

Solution 1. Try Restarting Your Computer

Many computer technicians’ first line of advice is “Have you tried turning it off and on again?” This is due to the fact that a restart of your computer will often fix any problems you may be experiencing. Just try this one thing first before you try anything else.

Step 1: A “hard restart” involves shutting down the computer completely (Start > Power > Shut Down) and waiting a few minutes before turning it back on.

Step 2: This allows the machine to shut down entirely before the reboot process begins.

Solution 2. Roll Back Windows Update

If this error appeared after installing a Windows update, then reverting to a previous version of Windows should fix the issue. Microsoft wisely included a “uninstall updates” option in Windows 10 in response to users’ seemingly endless complaints about issues with Windows updates.

Step 1: Go to Windows Update by selecting “Settings -> Update & Security” and then clicking “See update history.”

Step 2: To remove the updates, select “Uninstall.”

Step 3: You can right-click the updates in the list and choose “Uninstall” if they were released after the troubles began. (preferably the newest ones before the “bad system config” problems started appearing).

Solution 3. Check Your RAM and Hard Drive

A lot of people are intimidated by the idea of opening up their PC and fiddling with the hardware. The RAM and hard disk in your computer can be the root of the bad system config info problem if they are malfunctioning or poorly installed.

If you’re not afraid of opening your PC, check the RAM sticks are properly seated in the slots and the SATA connections are securely linked to the hard drive. A few minutes is all that should be needed to complete any of these inspections.

If you have more than one RAM stick, you might try using just one to see if the problem goes away.

If the error arises only when specific RAM modules are installed, then it is likely that one or more of those modules is causing the problem, and you may need to reduce the amount of RAM installed in your computer (and, down the line, look into buying new RAM).

After making sure the RAM and hard disk are installed correctly, you may verify their status by consulting the relevant recommendations we provide on this site. If you receive unfavorable feedback on either front, this may be the root cause of the faults, and you may want to consider replacing the relevant parts.

Solution 4. Update or Reinstall Drivers

It’s common for many problems to stem from drivers that are either incompatible or out of date. The worst thing that may happen is when BSoD errors, such the Bad System Config Info, pop up because of faulty drivers. Read the steps below to learn how to fix the issue:

Step 1: In Windows, open the Device Manager.

Step 2: Type “device management” into the Win key’s search bar.

Step 3: Choose “Action -> Check for hardware changes” in the Device Manager window, and then check to see if any devices have a yellow warning icon next to them. (You’ll find them in the menus beneath the main headings.)

Step 4: Right-click on the offending driver, then select “Update driver.”

Step 5: If the problem persists after doing so, right-click the driver and select “Remove device.” A system device (such the driver for your onboard Ethernet port) will be automatically reinstalled after a system restart.

Step 6: Reconnecting the device in issue or reinstalling the software will cause any third-party drivers to reinstall.

5. bcdedit Command

An erroneous or improperly configured system configuration is a common cause of the Bad System Config Info issue.

If the configuration file’s memory or processor values are incorrect, the error will show as well, blocking access to Windows 10 and Windows 11. You’ll need to access the Advanced Startup menu to fix this.

Step 1: Choose the Play button.

Step 2: To turn on, choose the power button.

Step 3: Hold down Shift and select Restart to restart.

Step 4: The “Choose an Alternative” menu will show up. Choose the option to Fix It.

Step 5: Click “Advanced Options” in the Troubleshoot menu.If you go to the “Advanced Options” menu, you can pick “Command Prompt.”

Step 6: After the restart, the blue screen with the Command Prompt prompt will appear. To proceed, you’ll need to sign in with one of your accounts. Once you’ve entered the correct password, press the Enter key.

Step 7: When prompted, type the lines below into Command Prompt:

bcdedit/deletevalue {default} numproc
bcdedit/deletevalue {default} truncatememory

Step 8: End Command Prompt.

Step 9: Try restarting Windows again.
