Bad System Config Info is a common bug checking error on Windows systems mainly caused by a malfunction of the system and registry files or the Boot Configuration Data (BCD) file. Some boot order files in the BCD, or even some older ones, may conflict with newer, stable files. When this occurs, the error otherwise known as the Blue Screen of Death (BSoD) occurs.
The bug checking error can also be caused by:
- defective material
- incorrect system settings
- a bad driver
- install an important update
However, most error messages often contain a description of the nature of the problem. Below are some proven solutions to help you fix Incorrect System Configuration Info error in Windows 10.
Check your RAM and hard drive
For some, it can seem intimidating to look inside your PC and start playing around with the physical components. However, the health and fit of your RAM and hard drive may be the cause of incorrect system configuration information error.
If you’re comfortable with opening up your PC, you can take a look inside to make sure your RAM is seated properly in the slots and that your hard drive’s SATA cables are securely connected as well. These checks should not take more than a few minutes.
Assuming your RAM and hard drive are properly installed, then you should check your RAM status and hard drive status, both of which we have guides on the site for. If you are performing poorly on either front, it may be the root of the errors and it may be time to look to replace the affected components.
Update or reinstall the drivers
Incompatible or outdated drivers are the cause of several problems. The worst thing bad drivers can do is report BSoD errors, such as incorrect system configuration information.
To resolve this problem, you need to go to Windows Device Manager (To win key, then type device manager). In the Device Manager window, click “Action -> Check for hardware changes” and then see if any yellow exclamation mark symbols appear next to any of the devices. (You’ll have to click the drop-down icons to find them.)
If you find faulty drivers, right-click on them, then click “Update Driver”. If the problem persists, right click on the driver and then click “Uninstall device”. If it is a system device (like your built-in Ethernet port driver), it will automatically reinstall itself after you restart your PC.
If it is a third-party driver, it will reinstall itself after reconnecting the device in question or after reinstalling the software.
bcdedit command
Very often, the Bad System Config Info error can appear when the system configuration is incorrect or not configured correctly. Moreover, if the memory and processors in the config file have the wrong value, the error will also appear, preventing access to Windows 10.
To resolve this issue, trigger Windows 10 to access the advanced start menu:
1. Click on Start.
2. Click on Power.
3. Press and hold Offset and click Restart.
4. The “Choose an option” screen is displayed. Select Troubleshoot.
5. In the Troubleshoot window, select “Advanced options”.
6. In the Advanced Options window, select Command Prompt.
7. Your computer will restart and then display the blue screen of the command prompt. You will be prompted to select an account to continue. Press Enter, and then type your password for this account.
8. Enter the following lines once the command prompt starts:
bcdedit/deletevalue {default} numproc bcdedit/deletevalue {default} truncatememory
9. Close the command prompt.
10. Restart Windows 10.
Correct the BCD file
If your BCD file is corrupt or damaged, Bad System Config Info error may appear and deny you access to Safe Mode and Windows 10.
To solve this problem, you need your bootable USB drive with Windows 10 or the installation DVD. You can also use the Media Creation Tool if you do not have a bootable USB drive.
Here’s what to do next:
1. Insert the bootable Windows 10 installation DVD and boot from it.
2. Windows 10 setup will start.
3. Click on Next.
4. Click on “Repair your computer”.
5. Select “Troubleshoot -> Advanced options -> Command prompt”.
6. Enter the following lines when starting the command prompt. (Press Enter after each line to execute it.)
bootrec /repairbcd bootrec /osscan bootrec /repairmbr
7. Close the command prompt.
8. Restart your computer.
Note: the last command you enter will delete and then recreate the master boot records. Be careful while using it.
Repair the registry
There are specific registry issues that can cause the error, but you can repair the registry to resolve it by doing the following:
1. Boot from the Windows 10 installation DVD.
2. Select “Troubleshoot -> Advanced options -> Command prompt”.
3. Enter the following lines when starting the command prompt. (Press Enter after each line to execute it.)
cd C:WindowsSystem32config ren C:WindowsSystem32configDEFAULT DEFAULT.old ren C:WindowsSystem32configSAM SAM.old ren C:WindowsSystem32configSECURITY SECURITY.old ren C:WindowsSystem32configSOFTWARE SOFTWARE.old ren C:WindowsSystem32configSYSTEM SYSTEM.old
Note: the folders for each of these commands are renamed when you press Enter, and once that is done Windows 10 will no longer use them. They can be deleted, but it’s better to rename in case you need to restore the system much later.
4. Then enter the lines below in the command prompt:
copy C:WindowsSystem32configRegBackDEFAULT C:WindowsSystem32config copy C:WindowsSystem32configRegBackSAM C:WindowsSystem32config copy C:WindowsSystem32configRegBackSECURITY C:WindowsSystem32config copy C:WindowsSystem32configRegBackSYSTEM C:WindowsSystem32config copy C:WindowsSystem32configRegBackSOFTWARE C:WindowsSystem32config
This process copies the registry backup and replaces the old files. Close the command prompt and restart your PC.
System Restauration
If the other methods don’t help, this might be one of your last two solutions to try.
1. Click on Start.
2. Click on Power.
3. Press and hold Offset and click Restart.
4. Select “Troubleshoot -> Advanced options -> System restore”.
5. Choose your username.
6. Follow the prompts on the screen.
7. Select the desired restore point.
8. Click Next and wait for the process to complete.
Reset Windows 10
This is the last solution to try if none of the others have worked. Before resetting, create a backup because once you reset Windows, all files will be deleted from C partition.
1. Click on Start.
2. Click on Power.
3. Press and hold Offset and click Restart.
4. Select “Troubleshoot -> Reset this PC”.
5. Select “Remove all -> Only the drive where Windows is installed -> Just delete my files.”
6. Click Reset and wait for it to complete the process. You will have a fresh install of Windows 10 once this is done.
Resetting should fix the problem if it was related to your PC software.
Despite its issues, we believe Windows 10 is still a great operating system. But if you are having other issues like faulty headphones or unusually high CPU usage in Windows 10, we’re here to help.
