  1. Update your drivers
  2. Use bcdedit command
  3. Fix the BCD file
  4. Fix the Windows Registry
  5. Perform System Restore / Windows 10 reset
  6. Check your hardware

Solution 1 – Update your drivers

Outdated or incompatible drivers can cause many issues. For example, if your drivers don’t work, you won’t be able to use certain hardware, and in worst case scenario, you’ll get a BSoD error such as BAD_SYSTEM_CONFIG_INFO.

Since many Blue Screen of Death errors are commonly caused by drivers, we strongly advise you to update your drivers as often as you can. In order to avoid all BSoD errors, be sure that all major components are up to date with latest drivers.

Downloading drivers is fairly simple, and all you need to do is to visit your hardware manufacturer’s website, locate your device and download the latest drivers for it.

After installing the latest drivers, BSoD errors should be resolved. Bear in mind that you’ll have to update as many drivers as you can in order to successfully fix this problem.

In order to fix BAD_SYSTEM_CONFIG_INFO and many other BSoD errors, it’s important that you update all drivers on your PC.

This can be a long process, especially if you do it manually, download TweakBit’s Driver Updater Tool (100% safe and tested by us) to do it automatically.

This tool is approved by Microsoft and Norton Antivirus. After several tests, our team concluded that this is the best automatized solution in order to prevent permanent damage to your system by downloading and installing the wrong driver versions.

Disclaimer: some functions of this tool are not free.

Alternatively, you can use our technician guide to update outdated drivers!

Solution 2 – Use bcdedit command

BAD_SYSTEM_CONFIG_INFO error can often appear if your system configuration isn’t correct.

If your system isn’t properly configured, and the number of processors and amount of memory in the configuration file doesn’t match the correct value, that will cause BAD_SYSTEM_CONFIG_INFO error.

To make things even worse, this error will prevent access to Windows 10 completely. Although this sounds rather serious, we can easily fix this issue by doing the following:

  1. Restart your computer while it boots. Repeat this step until you start Automatic Repair.
  2. Choose Troubleshoot > Advanced Options > Command Prompt.
  3. Once the Command Prompt starts, enter the following lines:
    • bcdedit/deletevalue {default} numproc
      Bad_system_config_info registry bcdedit/deletevalue {default} numproc
    • bcdedit/deletevalue {default} truncatememory
      Bad_system_config_info RAM bcdedit/deletevalue {default} truncatememory
  4. Close Command Prompt and try starting Windows 10 again.

Solution 3 – Fix the BCD file

If for some reason your BCD file gets corrupted or damaged, that can cause BAD_SYSTEM_CONFIG_INFO error, and you won’t be able to access Windows 10 or Safe Mode at all.

To complete this solution you’ll need a Windows 10 installation DVD or a bootable USB flash drive with Windows 10 on it.

If you don’t have bootable USB flash drive you can easily create one by using Media Creation Tool. To fix the BCD file, do the following:

  1. Insert the bootable DVD or USB flash drive and boot your PC from it.
  2. Windows 10 setup will start. Click Next and then click on Repair your computer.
  3. Choose Troubleshoot > Advanced Options > Command Prompt.
  4. When Command Prompt starts, enter the following lines and press Enter after each line in order to execute it:
    • bootrec /repairbcd
      Bad system config info on startup bootrec /repairbcd
    • bootrec /osscan
      Blue screen of death bad_system_config_info bootrec /osscan
    • bootrec /repairmbr
      Bad_system_config_info after update bootrec /repairmbr

It’s worth mentioning that the last command will delete Master Boot Records and recreate them, so be careful while using it. After you’re done, close Command Prompt and restart your PC.

Solution 4 – Fix the Windows Registry

Certain registry issues can cause this error to appear, therefore you might want to repair your registry. To do that, you just need to perform the following steps:

  1. Boot your computer from Windows 10 installation media. For more details on how to do that check the previous solution.
  2. Choose Troubleshoot > Advanced Options > Command Prompt.
  3. When Command Prompt opens, enter the following lines and press Enter after each line in order to run it:
    • CD C:WindowsSystem32config
    • ren C:WindowsSystem32configDEFAULT DEFAULT.old
    • ren C:WindowsSystem32configSAM SAM.old
    • ren CWindowsSystem32configSECURITY SECURITY.old
    • ren C:WindowsSystem32configSOFTWARE SOFTWARE.old
    • ren C:WindowsSystem32configSYSTEM SYSTEM.old

    By entering these commands you’ll rename all these folders. After you rename them, Windows 10 won’t be able to use them anymore. You can also delete them, but it’s always better to rename them in case you need to restore them later.

  4. Now enter the following lines into 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
  5. This will copy the registry backup and replace the old files. Close Command Prompt and restart your computer.

Solution 5 – Perform System Restore / Windows 10 reset

If none of the previous solutions were helpful, you might want to try performing System Restore. To perform System Restore, do the following:

  1. Restart your computer couple of times while it boots. This will start Automatic Repair process.
  2. Select Troubleshoot > Advanced Options > System Restore.
  3. Select your username and follow the instructions.
  4. Select the restore point you wish to restore to and click Next.
    Bad_system_config_info hard drive restore the system from a restore point
  5. Wait for the System Restore process to finish.

If System Restore didn’t fix the BAD_SYSTEM_CONFIG_INFO error, try performing Windows 10 reset. Before you perform Windows 10 reset be sure to create backup because the reset process will delete all files from your C partition. To start the reset process do the following:

  1. Start Automatic Repair process by restarting your computer few times.
  2. Choose Troubleshoot > Reset this PC.
  3. Select Remove everything > Only the drive where Windows is installed > Just remove my files.
  4. Click the Reset button and wait for the process to finish.

In order to complete the Windows 10 reset, you might need Windows 10 installation media, so be sure to have one. After the reset process is completed, you’ll have fresh installation of Windows 10.

If the BSoD error was caused by a software, it should be fixed after the reset, but if the BSoD error appears again, it means that you have a hardware issue.

Solution 6 – Check your hardware

Most commonly the BSoD errors are caused by faulty RAM, so be sure to check your RAM first.

Users reported that BAD_SYSTEM_CONFIG_INFO error can also be caused by a faulty hard drive, and according to users, replacing the hard drive fixed the problem.

It’s worth mentioning that almost any component can cause this error, so be sure to perform a detailed hardware inspection.

BAD_SYSTEM_CONFIG_INFO isn’t serious as other BSoD errors, and it can be easily fixed.

Users reported that this error was fixed by using bcdedit or by fixing Windows Registry, so be sure to try those solutions.
