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Outdated or incompatible drivers can cause many issues.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 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.

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.

Alternatively, to avoid manually updating drivers and possibly downloading the wrong one, we recommend using a dedicated tool such as DriverFix to automatically get the necessary updates.

This tool will help with exactly this job – scan your system for outdated drivers and find the compatible software to replace them.

Downloading and installing DriverFix only takes a couple of seconds, and no extra tweaking is necessary. It will start to scan your PC for driver problems right away.

At the end of the process, you will get a list of recommended drivers to install.

You only need to click on the Update All button to install all the drivers or click on the checkboxes corresponding to each driver if you want to install them individually.

2. Use the bcdedit command

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

3. Fix the BCD file

1. Insert the bootable DVD or USB flash drive and boot your PC from it.
2. Click on Next and then click on Repair your computer.
3. Choose Troubleshoot, then Advanced Options, and select Command Prompt.
4. Enter the following lines and press Enter after each line in order to execute it:
   • bootrec /repairbcd
   • bootrec /osscan
   • bootrec /repairmbr

Note: 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 a bootable USB flash drive you can easily create one by using Media Creation Tool.

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.

4. Fix the Windows Registry

1. Boot your computer from Windows 10 installation media (check the previous solution).
2. Choose Troubleshoot, then Advanced Options, and select Command Prompt.
3. Enter the following lines and press Enter after each line in order to run it:

CD C:\Windows\System32\config

ren C:\Windows\System32\config\DEFAULT DEFAULT.old

ren C:\Windows\System32\config\SAM SAM.old

ren C:\Windows\System32\config\SECURITY SECURITY.old

ren C:\Windows\System32\config\SOFTWARE SOFTWARE.old

ren C:\Windows\System32\config\SYSTEM SYSTEM.old

Note: 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.

1. Enter the following lines into Command Prompt:

copy C:\Windows\System32\config\Reg\Back\DEFAULT C:WindowsSystem32config

copy C:\Windows\System32\config\Reg\Back\SAM C:WindowsSystem32config

copy C:\Windows\System32\config\Reg\Back\SECURITY C:WindowsSystem32config

copy C:\Windows\System32\config\Reg\Back\SYSTEM C:WindowsSystem32config

copy C:\Windows\System32\config\Reg\Back\SOFTWARE C:WindowsSystem32config

2. This will copy the registry backup and replace the old files. Close Command Prompt and restart your computer.
