Does this look familiar?

If you’re using Windows 10, you’ve probably encountered some BSOD errors. BAD_SYSTEM_CONFIG_INFO is one of those BSOD error code. Don’t worry anymore. You’re able to fix it with this guide.

How do I fix it? 

Here are 4 solutions you can try. You may not have to try them all; just work from the top down until you find the one that works. 

IMPORTANT: You’ll need to be logged into Windows on the problem computer to try any of these solutions. If you can’t log into Windows, restart it in Safe Mode, then try these solutions.

Method 1: Update all your available drivers 
Method 2: Fix the BCD file
Method 3: Fix the Windows Registry

Method 1. Update all your available drivers 

This error is probably being caused by outdated or missing drivers. You should verify that all your devices have the right driver, and update those that don’t.  If you’re not comfortable playing around with drivers manually, you can do it automatically with Driver Easy.

Driver Easy will automatically recognize your system and find the correct drivers for it. You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks (and you get full support and a 30-day money back guarantee):

2) Run Driver Easy and click Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.

3) Click the Update button next to a specific driver to automatically download and install the correct version of this driver (you can do this with the FREE version).

Or click 
Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).

4) Reboot your Windows 10 to see if it works.

Method 2. Fix the BCD file

This error could be also caused by the demaged BCD(Boot Configuration Data) file. So if your Win 10 can’t enter safe mode to fix the error, be sure to try to fix the BCD file.
