Windows and prevents the operating system from starting. We will tell you about the reasons for its appearance and ways to eliminate the problem.
What does the BAD SYSTEM CONFIG INFO error mean?
The error appears on a blue screen and indicates a discrepancy between the registry data and the actual system configuration. It can appear both during operation and when loading the PC/laptop. The latter is especially unpleasant, since in this case you will not be able to use the OS until the problems are fixed.
As for the reasons for the BAD SYSTEM CONFIG INFO error, the main ones include:
- Incorrect BIOS settings;
- Incorrect Windows registry settings;
- Damage to system files;
- OS conflict with new hardware.
How to fix BAD SYSTEM CONFIG INFO error
Unfortunately, it is very difficult to immediately determine the cause of the error, so we will act by the method of elimination.
Reset BIOS to factory settings
It’s better to start with the simplest. Even if you haven’t entered the BIOS and haven’t changed anything there.
Procedure:
- Turn the device off completely and then turn it on again;
- Immediately start pressing the desired key until you get to the menu. Usually, the Del or F8 keys are responsible for entering the BIOS, but sometimes it can be F2 and F12;
- The BIOS design also varies on different devices. Look for the line with the word Defaults and click on it. Often, the F9 key is responsible for resetting to factory settings;
- Confirm saving the parameters, then wait for the OS to load.
If the error does not disappear, then we proceed further.
Updating drivers for new equipment
If the error appeared after installing a new device (for example, a video card), then update the drivers to the current version. It is best to download them from the manufacturer’s website, but you can also update through the “Device Manager”. To do this:
- Right-click on the Start menu and select Device Manager;
Select the required device from the list, right-click on it, and then click “Update driver”;
- In the menu that opens, click on “Search for drivers automatically”.
The problem remains? Let’s move on.
Fixing the registry
If the problem is caused by incorrect data in the registry, there is a chance to fix it by loading Safe Mode. Usually, in this case, Windows replaces the data with the current one.
To do this:
- Turn the device off completely and then turn it on again;
- Press F8 until you find yourself in a black menu with many options. If the same key is responsible for entering the BIOS, then you will have to press it after the splash screen disappears from the screen;
- Select the very first item – “Safe Mode”;
- Wait until the OS is loaded, then press Win + R;
- Type msconfig and press Enter;
- Open the “Downloads” tab and uncheck “Safe Mode”;
Still bothered by the error? Don’t worry – there are still a few ways to get your device back to working order.
Loading Last Known Good Configuration
Procedure:
- Turn the device off completely and then turn it on again;
- Press F8 until you find yourself in a black menu with many options. If the same key is responsible for entering the BIOS, then you will have to press it after the splash screen disappears from the screen;
- Select Last Known Good Configuration.
The system will reboot. If you are lucky, the error will disappear. If not, then we proceed further.
Using the Recovery Environment
You can try to roll back Windows to an earlier state using restore points. If the error occurs randomly and the system boots, then do the following:
If the OS does not boot, you can try to boot the recovery environment in the same way as the BIOS – using the hot keys provided by the manufacturer. Usually, all laptops have this function. Do some research on the Internet and find out how to get into the recovery environment on your device.
You can also use a bootable USB flash drive. You can read more about this here .
What is described in this section is useless in a situation where the user has deleted all restore points or disabled this function altogether.
Reinstall Windows
The most radical method in case all other methods have failed. If Windows boots and you have not deleted the recovery partition , then do the following:
