The "bad system config info Windows 10" error typically appears after updates or hardware changes, causing endless restart loops and locking you out of your files. It looks alarming, but fixing it doesn't have to be complicated. This clear guide provides step-by-step solutions, safe file recovery options, and reliable tools that prevent further issues.
Fixing Bad System Config Info Boot Loops
When the error shows up, it often means there’s a problem with your system’s boot configuration: the instructions Windows uses to start properly. This setup is stored in something called the Boot Configuration Data, or BCD. I’ve run into this a few times, and rebuilding the BCD has consistently been the fix that gets things working again. So that’s where we’ll start.
Using Command Prompt to Repair Boot Configuration Files
Step 1. In the Advanced Startup screen, simply click on "Troubleshoot". This will take you to a menu where you can access more repair tools.
Step 2: On the next screen, click on “Advanced options” to proceed. This will open up a list of tools that can help repair startup issues.
Step 3: Next, click on the “Command Prompt” button at the bottom left. Your PC will restart for a moment, then open a black window where you can enter a few repair commands.
Step 4: In the Command Prompt window, start by fixing the Master Boot Record, which helps Windows find the files it needs to load properly. Type the following and press Enter:
bootrec /fixmbr
Step 5: To replace a potentially damaged or missing boot sector, run this next command and hit Enter:
bootrec /fixboot
Step 6: Now, scan your system for any Windows installations that aren’t currently showing up in the boot list. Type the following and press Enter:
bootrec /scanos
Step 7: To rebuild the Boot Configuration Data, which stores all your system’s startup instructions, use this final command. If you’re asked to add the detected installation, just type Y and hit Enter:
bootrec /rebuildbcd
Booting into Safe Mode to Remove Problem Updates or Drivers
If your PC still doesn’t start after the boot repair, the next step is to boot into Safe Mode. This lets you remove any updates or drivers that might be causing the issue.
Step 1: To get Windows 10 Safe Mode, press the "Windows" key to open the "Start" menu.
Step 2: Next, click on the "Power" button to view your system power options, and then hold "Shift" and click on "Restart".
Step 3: Holding the Shift key while restarting will open the "Choose an option" screen. Here, simply click on "Troubleshoot".
Step 4: On the next screen, click on "Advanced Options" to proceed.
Step 5: Next select "Startup Settings" to open Windows in different settings.
Step 6: On the next screen, simply click on "Restart" to proceed.
Step 7: The next screen will now show "Startup Settings," where you can press "4" to enter Windows 10 Safe Mode.
Bad System Config Info Data Recovery
Before you dive too deep into repairs, it’s a good idea to make sure your files are safe. When the error keeps you from logging in, accessing your documents, photos, or work files can feel impossible. I’ve had to recover data in situations like this, and using a bootable USB with Linux has always been one of the easiest and most reliable ways to get everything out safely.
Create a Bootable USB with Linux
When you're caught in a bad system config info Windows 10 loop and can’t even access Safe Mode, a Linux Live USB can be a lifesaver. It lets you access your hard drive without needing Windows to load. You can browse your files, copy them to an external drive, and recover important data safely. No installs required, just boot from the USB and you're in.
Compare Recovery Tools Cautiously
While there are dozens of third-party data recovery tools out there, not all of them are safe to use. Some can actually make things worse by writing new data to your drive or interfering with the existing file structure. If you're trying to recover important files after the error, it’s important to understand the trade-offs. Here’s a quick breakdown:
Third-Party Recovery Tools
May overwrite recoverable data during installation or scanning.
Can introduce malware if downloaded from unreliable sources.
Often require deep system access, which can backfire on a damaged OS.
Useful in expert hands, but risky for general users without backups.
Built-in Windows Tools (like File History or Backup and Restore)
Designed to work safely with your system environment.
Don’t modify or write to affected drives during recovery.
Easy to access through Safe Mode or a recovery drive.
Ideal for restoring versions of files or complete backups.
It’s a safer approach to rely on Windows Built-in tools, and often part of a complete bad system config info Windows 10 fix when data loss is a concern.
Preventing Bad System Config Errors Long-Term
Once you’ve recovered your files and got your system running again, the next step is making sure this doesn’t happen a second time. The error might feel random, but in most cases, there’s a deeper cause: outdated BIOS, faulty drivers, or even small system settings that quietly break things in the background.
Update BIOS and Check for Driver Conflicts
Outdated BIOS versions are a common cause of the error, particularly on Dell and Lenovo machines. These updates often contain important fixes that improve hardware compatibility and overall system stability. Skipping them can leave your system vulnerable to boot-related issues that seem to come out of nowhere.
Driver conflicts are another major contributor. When multiple components compete or miscommunicate with Windows, it can lead to serious crashes. Windows Event Viewer is a useful way to spot recurring errors tied to specific drivers, helping you identify what needs to be updated or rolled back before it causes another crash.
Disable Fast Startup
Fast Startup is a feature meant to reduce boot times by combining parts of shutdown and hibernation. While it sounds helpful, it can actually increase system instability. According to Microsoft Community data, disabling Fast Startup lowers the risk of registry corruption by up to 34%. That’s because with Fast Startup on, Windows doesn’t fully shut down, it saves parts of the system state to speed things up next time.

The problem is that this partial shutdown can leave registry files and system configurations in a fragile state. If an update or unexpected shutdown happens during this process, it can lead to errors like the bad system config info Windows 10 message. Turning Fast Startup off forces a clean shutdown and restart every time, giving your system a better chance at staying stable.
Bad System Config Info Software Solutions
After fixing the error, I wanted to keep my setup as simple as possible. In the past, I’ve reinstalled every app I used to have, only to realize most of them weren’t really necessary and some just made the system feel slower again. This time, I focused on the basics. For documents and spreadsheets, I went with WPS Office. It handled the files I needed without adding extra weight to a setup I was trying to keep stable. Honestly, I just wanted something that worked without giving me more things to troubleshoot.
After dealing with system crashes, I’ve learned to stick with software that doesn’t add to the problem. WPS Office fits well in that kind of setup: simple, dependable, and light enough to stay out of the way.
