Bad System Config Info is a common bug check error on Windows systems, caused mainly by a malfunctioning of the system and registry files or the Boot Configuration Data (BCD) file.
Some boot order files in the BCD, or even some older ones, may conflict with newer, stable files. When this happens, the error otherwise known as the Blue Screen of Death (BSoD) occurs.
The bug check error can also be caused by:
- faulty hardware
- incorrect system settings
- a bad driver
- installing an important update
However, most error messages will often have a description of what the problem may be. Below are some tried and tested solutions to help you fix a Bad System Config Info error in Windows 10 and 11.
How to fix ‘Bad System Config Info’ error in Windows
- Try Restarting Your Computer
There’s a reason that many IT people jokingly ask, “Have you tried turning it off and on again?” It’s because, in many cases, a simple restart can clear the issues your PC is having. Before you try anything else, give this suggestion a try.
Ideally, you should do a “hard restart” by going to “Start -> Power -> Shut Down,” and then waiting a few minutes before turning the computer back on. This gives the system time to power down completely before rebooting.
- Roll Back Windows Update
If this error started occurring soon after a Windows update, then that probably is where your problem lies, and the solution should be simple: roll back the Windows update!
- Check your RAM and Hard Drive
For some, it may seem daunting to look inside your PC and start twiddling around with the physical components. However, the health and fitting of your RAM and hard drive can be the cause of the bad system config info error. If you’re comfortable with opening up your PC, you can take a look inside to make sure that your RAM is correctly fitted into the slots and that your hard drive SATA cables are properly connected too.
- Update or Reinstall Drivers
Incompatible or outdated drivers are a source of several issues. The worst thing bad drivers can do is bring up BSoD errors, such as the Bad System Config Info.
- System Restore
If the other methods don’t help, this may be one of your last two solutions to try. Note that you will not be able to use this method if you don’t have saved restore points to pull from. However, the system will let you know if you don’t.
- Reset Windows 10/Windows 11
This is the last solution to try if none of the others worked. Before resetting, create a backup, as once you reset Windows, all files will be deleted from the C partition.
