Look around.

1. Ensure Your RAM and Hard Drive

The bad system config information error may be caused by a lack of RAM or a malfunctioning hard drive. Take a look at the interior of your computer to determine if it’s in good working order. Also, make sure that the SATA cables for the hard drives are connected correctly.

If there are more than one RAM stick, remove the rest and leave only one. It’s possible that your RAM sticks are malfunctioning if the error disappears after removing any RAM sticks. Check the health of the RAM and hard drives if they are connected correctly. If a problem is discovered, replace the faulty parts.

If your RAM and hard drive are in great working order, then there may be an other issue at play. Moving on to the next approach, shall we? Second, update or reinstall your driver. There are many reasons why this error occurs, including faulty or incompatible drivers.

Uninstalling any drivers that don’t seem to be working properly or are incompatible is the best way to fix this. To do so, here are the steps:

Step 1: The first step is to open the window device manager by first pressing the start button and typing device manager in the search field. Next, under the device manager, click the Action button.

Step 2: Finally, check to see if any yellow exclamation marks appear next to any devices that have recently changed.

Step 3: Click “Update Driver” in the context menu of any malfunctioning drivers. Right-click the driver and select “Uninstall device” if it doesn’t work.

If you have a defective driver, it will be removed. Once the computer has been restarted, the driver will be immediately re-installed.

2. Command For Editing BCD

This problem can be caused by an incorrect system configuration, such as an incorrect number of CPUs or an incorrect quantity of memory. A BAD SYSTEM CONFIG INFO issue can be caused by overheating devices when a large number of CPUs are being used.

As a result, the machine will not boot up if the memory amount is incorrect. This can be fixed by following the steps outlined in the following paragraphs: –

Step 1: The first step is to press the power button on the start button. Afterwards, press the shift button for a long time and then tap restart.

Step 2: From the “Choose an option” screen, pick Troubleshooting. In the “advanced option,” pick “Command Prompt” to continue. After the computer has restarted, you will be able to select an account from the Command Prompt blue screen that appears.

Step 3: Finally, input your password by pressing the enter key. The following commands should be typed in:

use bcdedit/deletevalue to remove the default value

using bcdedit to remove the default value deleted values in the truncatememorybcdedit/deletevalue numproc

BCDedit/deletevalue default> is the command to remove the value. truncatememory

edit/deletevalue numproc is the default option.

using bcdedit to remove the default value deleted values in the truncatememorybcdedit/deletevalue numproc

using bcdedit to remove the default value truncatememory

Step 4: Restart Windows and shut down the command prompt.

3. Restore The BCD Files

Corrupt BCD files can also cause this issue and prevent you from booting into safe mode or even using the operating system in the first place. Follow these steps to make it right:

Step 1: Insert the bootable DVD or USB flash drive into your PC and start it up from there. Select Next and then click on the Repair Your Computer option. Select Troubleshooting and then click Advanced options.

Step 2: Finally, type the following lines into the command prompt and hit enter after each one.

/repairbcd / bootrec

osscan / bootrec

/repairmbr /bootrec

A Windows 10 installation DVD or bootable USB flash driver with Windows 10 is required for the installation of this fix. It’s easy to make a media creation tool if you don’t have one.

The last command will also destroy and recreate Master Boot records, so exercise caution when using it. You can now exit Command Prompt and restart your computer.

5. Make Sure Your Registry Is Up To Date

The Windows registry is where system and application settings and data are stored. Windows startup, hardware loading, and some Windows apps are all controlled by registers. It’s possible that a problem with the registry is to blame for this error. Following these actions will help:

Step 1: Windows 10 or 11 DVDs can be booted from at this point. Troubleshoot and select Advanced Options are the next steps. Enter the following command lines into the command prompt:

cd Windows System32 Configuration

default.ini in C:WindowsSystem32.config

renew C:Windows>System32>SAM SAM and the old C:Windows>System32>config files.

Windows System Configuration Editor (MS config)

Folders will be renamed and cannot be used again after pressing Enter after each line. They can also be removed.

Step 2: Next, type in the following lines:

C:WindowsSystem32configRegBackDEFAULT should be copied to C:WindowsSystem32.

When you copy RegBackDEFAULT to C:Windows System32config, you’ll get the same results.

C:WindowsSystem32configRegBackSAM should be copied to C:WindowsSystem32.

RegBackSECURITY is copied to C:Windows>System32>config.

To achieve this, simply copy the Registry Backup System settings from one Windows System Folder to another.

make a duplicate of C:WindowsSystem32configRegBackSOFTWARE

All old files will be replaced and a backup of the registration will be created. Finally, exit Command Prompt and restart your computer..

6. Restoring The System

This issue can also be fixed by doing a system restore. To do so, here are the steps:

Step 1: Start by pressing Start and then pressing Power.Long press the shift key and choose restart. Next, go to the troubleshooting section and select the advanced tab.

Resetting Windows is the only option left if none of the other methods worked. Performing a factory reset will fix this problem and all other issues.

To perform a factory reset, follow these instructions:

Step 1: The first step is to press the start and power buttons. Restart your computer by holding down the shift key for a long time. Next, select’reset this PC’ from the troubleshoot menu.

Step 2: Afterwards, select “Only derive where Windows is installed and then remove my stuff” from the drop-down menu that appears and click “Remove everything.” To finish, click the reset button one again and then wait for the process to be finished.
