How to Fix the BAD SYSTEM CONFIG INFO Error in Windows

The BAD SYSTEM CONFIG INFO error on Windows can be frustrating, especially when it appears suddenly and without an obvious cause. Typically, this error is linked to incorrect system file configurations or damaged registry entries. In this guide, we'll explore common causes of this error and outline several effective methods for resolving it.

Causes of the BAD SYSTEM CONFIG INFO Error

The BAD SYSTEM CONFIG INFO error usually occurs due to one or more of the following reasons:

  • Incorrect or damaged entries in the Windows registry;
  • Errors in the Boot Configuration Data (BCD) file;
  • Corruption of system files after Windows updates;
  • Hardware issues, such as problems with RAM or the hard drive;
  • Software conflicts, such as incompatible drivers or antivirus software.

Methods to Fix BAD SYSTEM CONFIG INFO

1. Restart in Safe Mode

First, try restarting your computer in Safe Mode to check if third-party software is causing the issue. Here’s how to boot in Safe Mode:

  1. Restart your computer while holding down the Shift key.
  2. Select Troubleshoot > Advanced options > Startup Settings.
  3. Choose Restart, then press F4 to boot in Safe Mode.

If the error does not appear in Safe Mode, a third-party program, such as a driver or antivirus, is likely causing the issue.

2. Repair the BCD File

The BAD SYSTEM CONFIG INFO error often stems from issues with the Boot Configuration Data (BCD) file. To repair it, follow these steps:

  1. Boot from a Windows installation disk and select Repair your computer.
  2. Go to Command Prompt.
  3. In the command prompt, enter the following commands:
bootrec /repairbcd
bootrec /osscan
bootrec /repairmbr

These commands will scan and repair any necessary boot components for Windows.

3. Repair System Files with SFC and DISM

Using the SFC and DISM commands can repair corrupted system files. To do this:

  1. Open Command Prompt as an administrator.
  2. Type sfc /scannow and wait for the scan to complete.
  3. Then run DISM /Online /Cleanup-Image /RestoreHealth.

After completing these commands, restart your computer and check if the issue is resolved.

4. Check the Hard Drive and RAM

Sometimes, this error can be due to hardware issues. To check for these:

  • For hard drive errors: In Command Prompt as administrator, type chkdsk /f /r.
  • For RAM issues: Press Win + R, type mdsched.exe, and choose Restart and check for problems.

5. Use System Restore

If previous methods haven’t resolved the issue, try using System Restore to revert to an earlier point when your computer was error-free:

  1. Open Control Panel, navigate to System and Security > System Restore.
  2. Select Start System Restore, choose a restore point, and follow the on-screen instructions.
