How do I fix the BAD SYSTEM CONFIG INFO BSoD error?

1. Fix the BCD file

  • Insert the bootable DVD or USB flash drive and boot your PC from it. If you don’t have one, we have an excellent guide on how to create a bootable media.
  • Click on Next and then click on Repair your computer.
  • Choose Troubleshoot.
  • Then Advanced Options, and select Command Prompt.
  • Enter the following lines and press Enter after each line in order to execute it:
  • bootrec /repairbcd
  • bootrec /osscan
  • bootrec /repairmbr

It’s worth mentioning that the last command will delete Master Boot Records and recreate them, so be careful while using it. 

  • bootrec /repairbcd
  • bootrec /osscan
  • bootrec /repairmbr

After you’re done, close Command Prompt and restart your PC, then check if the error persists. If the BCD file was the problem, it should have been resolved.

2. Edit the BCD file

  • Restart your computer while it boots. Repeat this step until you start the Automatic Repair.
  • Choose Troubleshoot.
  • Then select Advanced Options and start Command Prompt.
  • Enter the following lines:
  • bcdedit/deletevalue {default} numproc
  • bcdedit/deletevalue {default} truncatememory
  • Close Command Prompt and try starting Windows 10 again.

When you encounter the BAD SYSTEM CONFIG INFO error in Windows 10, your computer may have damaged files.

3. Update your drivers

  • Press the Start button, type device manager, and select the app from the results.
  • Expand the sections and look if there is a device marked with an exclamation symbol next to it, right click on it and select Update driver.
  • Now click on Search automatically for drivers.
  • The system will look for any new drivers and if it finds one, it will install it. If not, click on Search for updated drivers on Windows Update.
  • First, click on the Check for updates button to see if there are new Windows updates you should install.
  • If the system is up to date, click on View all optional updates.
  • Next, select the Driver updates section, check the boxes for any new drivers and click the Download and install button.
  • You should perform the steps for all the drivers, even if they don’t have the exclamation mark, just to be on the safe side.

Outdated or incompatible drivers can cause many issues.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 the worst-case scenario, you’ll get a BSoD error such as BAD_SYSTEM_CONFIG_INFO.

This is why, in order to avoid all BSoD errors, be sure that all major components are up to date with the latest drivers.

If updating the drivers from Device Manager doesn’t fix the problem, visit your hardware manufacturer’s website, locate your device, and download the latest drivers for it.

Some PC issues are hard to tackle, especially when it comes to corrupted repositories or missing Windows files. If you are having troubles fixing an error, your system may be partially broken.
