A Blue Screen of Death (BSoD) is always a pain in the neck for Windows 10 users. And, it becomes more problematic when your Windows 10 computer faces the BAD_SYSTEM_CONFIG_INFO BSoD error.

Fixing a Blue Screen of Death error on Windows 10 is not easy. For fixing the BAD_SYSTEM_CONFIG_INFO error, Windows 10 users need to know what triggered the error and how one can avoid facing this error in the future.

Here’s a complete guide on how to fix BAD_SYSTEM_CONFIG_INFO error on Windows 10.

Why does BAD_SYSTEM_CONFIG_INFO error occur on Windows 10?

Before trying out the solutions, let’s find out what factors can trigger this STOP code error “BAD_SYSTEM_CONFIG_INFO” on your Windows 10 system.

To decode this BSoD error, I uncovered various issues with a Windows 10 computer that can potentially cause the BAD_SYSTEM_CONFIG_INFO error.

Bad Registry: In most cases, a corrupted Windows Registry can trigger this error. If your Windows 10 contains a bad registry, it is a serious problem. It could not only cause this BSoD error but may also trigger more STOP code errors in the future.

Hardware Issues: Hardware components facing failures can cause the BAD_SYSTEM_CONFIG_INFO on Windows 10. Hardware failure in your computer’s RAM, connected drives, internal Hard Drives, system drivers, processors, and other hardware components can trigger this error.

System Booting Problems: It is commonly found that Windows 10 computers fall in a loop of a system reboot. After facing the BAD_SYSTEM_CONFIG_INFO error, a Windows 10 computer gets stuck into rebooting itself over and over. Sometimes, users have reportedly faced the BAD_SYSTEM_CONFIG_INFO error only during the startup or boot up time on their Windows 10 computers.

Faulty Updates: Recently-installed updates could cause this error. In Windows 10, there are several updates causing system failures. You need to be sure if an update has caused the BAD_SYSTEM_CONFIG_INFO error on your PC before uninstalling.

Harmful System Files: The error can also occur when apps on your Windows 10 get infected by a virus or malware. Files such as rdyboost.sys, bad_system_config_info ntoskrnl.exe, classpnp.sys, and NTFS.sys have reportedly been the root cause of such BSoD errors.

Now, I have a few ways to troubleshoot the BAD_SYSTEM_CONFIG_INFO error on Windows 10. It is a different approach than fixing the BSoD error permanently.

Troubleshoot - BAD_SYSTEM_CONFIG_INFO error

The method shows how to troubleshoot BAD_SYSTEM_CONFIG_INFO error on a Windows 10 PC. Follow these simple instructions and get rid of the Blue Screen of Death instantly.

It involves two steps –

1. Boot in Safe Mode

Click on the ‘ Start’ icon and press the Power button on your computer at the same time. Hold-press the Shift key , click on Restart and select ‘ Safe Mode ’ to boot your Windows 10. Now, restart your computer in normal mode and you won’t face the BAD_SYSTEM_CONFIG_INFO error.

2. Rebuild your Windows

If the error persists, boot your Windows 10 in Safe Mode again. This time, go to ‘ Troubleshoot ’ from Boot Options menu and select ‘ Windows System Restore ’. It repairs your Windows 10 back to the default state.

Troubleshooting this error won’t fix your PC completely. You may still face the BAD_SYSTEM_CONFIG_INFO error later. You need solutions that can permanently solve this STOP code error.

How to Fix BAD_SYSTEM_CONFIG_INFO error on Windows 10

You have to know why BAD_SYSTEM_CONFIG_INFO error occurred on your computer. Based on that, you can try the fixes below –

1. The Registry Fix

Windows Registry issues are the most common causes of BSoD errors. To repair a registry, you need to navigate exactly to the corrupted registry key and remove it.

To fix the corrupted Windows Registry, you need to open the Boot Options menu (shown earlier).

In the Boot Options menu , go to Troubleshoot
Click on Advanced Options and select Command Prompt (program)
When the Command Prompt window opens, enter the following command-lines and press the Enter key after each line

CD C:WindowsSystem32config
ren C:WindowsSystem32configSAM SAM.old
ren C:WindowsSystem32configDEFAULT DEFAULT.old
ren C:WindowsSystem32configSOFTWARE SOFTWARE.old
ren CWindowsSystem32configSECURITY SECURITY.old
ren C:WindowsSystem32configSYSTEM SYSTEM.old

You have renamed these registry folders, so you can go further and delete them
Type the following commands one by one and press the Enter key after each line

copy C:WindowsSystem32configRegBackSAM C:WindowsSystem32config
copy C:WindowsSystem32configRegBackDEFAULT C:WindowsSystem32config
copy C:WindowsSystem32configRegBackSYSTEM C:WindowsSystem32config
copy C:WindowsSystem32configRegBackSECURITY C:WindowsSystem32config
copy C:WindowsSystem32configRegBackSOFTWARE C:WindowsSystem32config

Close the Command Prompt and restart your Windows 10 PC

Now, this registry cleanup would replace the old files and also create their backup. You can resume working on Windows 10 and see if you face the error.

2. Edit the BCD File Manually

The BAD_SYSTEM_CONFIG_INFO error occurs due to issues with Boot Configuration Data (BCD) files on your computer. You can edit these BCD files to fix the BSoD error.

This solution works when your computer isn’t properly configured. Simply put, a mismatch between the amount of memory and the number of processors causes this BAD_SYSTEM_CONFIG_INFO error. By editing the BCD file, you can set a correct value to match your system configurations.

Open the Boot Options menu
Click on Troubleshoot and choose ‘ Advanced Options ’
Select the ‘ Command Prompt ’ program
In the Command Prompt window, type “ bcdedit/deletevalue {default} numproc ” and hit the Enter key

Now, type the next command – bcdedit/deletevalue {default} truncatememory and press the Enter key
This repairs your BCD files automatically

You can close the Command Prompt window, restart your computer in normal mode and see if you still face the BSoD error.

These changes are put to effect, and the edited BCD file automatically solves the STOP code error.

3. Recreate BCD File

If the BCD files are damaged beyond repair, you can rebuild them automatically. With Command Prompt, you can restore new BCD files in Windows 10 installation media.

To restore BCD files,

Boot your PC in Safe Mode
In the Boot Options menu, navigate to Troubleshoot > Advanced Options
Here, open the Command Prompt program
Type the following commands and press Enter key after each line to execute the respective command –

bootrec /repairbcd
bootrec /osscan
bootrec /repairmbr

Close the Command Prompt window and restart your PC in normal mode. This can possibly fix the BAD_SYSTEM_CONFIG_INFO error on all Windows 10 computers.

4. Check Hardware/Update Driver

An outdated hardware component has always something to do with STOP code errors like BAD_SYSTEM_CONFIG_INFO. Get updates for all system adapters and drivers on your Windows 10

You can choose from the best Driver Updaters for Windows 10 and update them automatically.

To update drivers manually,

Press the Windows + R keys
Open the Run dialog box and type “ devmgmt.msc ”

Press the Enter key
Use the Tab key to navigate system drivers in the Device Manager window
Right-click on active drivers and click on Update Driver Software from the menu
Alternately, you can also press the Shift key and instantly press the F10 key
Follow the onscreen instructions
Select the option that says – Search automatically for updated driver software
Restart your PC thereafter

This could possibly solve the BAD_SYSTEM_CONFIG_INFO error permanently. It is the simplest fix of all.

5. System Restore

Your last option is rebuilding your Windows 10 in its earlier state. By creating a restore point , you can repair BSoD errors and bring your computer back to normal.

Once the restore point is created,

Click on the Start menu button
Type “ control panel ”
Open it from the results
Search for “ recovery ” (in the Control Panel search box)

Choose as follows - Recovery > Open System Restore > Next

If you’re OK with the deletions , select Next and Finish

System Restore takes time, and it may have an effect on newly-installed apps and recent system updates. It is advised to go for this fix only when the rest fail.
