Bad System Config Info Windows 10 Won’t Boot Blue screen (Fix)

Published by Alvin Nyau - Updated on

The Bad System Config Info error, or often seen as BAD_SYSTEM_CONFIG_INFO, is a blue screen of death STOP code error in Windows 10. This particular BSOD error can be caused by broken registry, incorrect system or hardware settings or hardware failure.

The Bad System Config Info blue screen error can happen during Windows 10 startup, after crashing in middle of a game or full-screen app, after Windows Update (particularly Windows April 2018 update version 1803, or any future update), or after you’ve made some changes to the registry or hardware settings.

This guide will show you how to fix the “Bad system config info” error in Windows 10 without booting into Windows.

Fix: Bad System Config Info Windows 10 BSOD error

Step 1: Boot into Command Prompt

Assuming you can’t boot into Windows 10 due to the BAD_SYSTEM_CONFIG_INFO blue screen error, you have to boot to Windows Recovery in order to access to the Command Prompt tool.

Here’s a trick to force boot your Windows 10 into Windows Recovery Environment. Switch on your computer. As soon as it starts to load Windows (in the Windows loading logo screen), press the restart button (physical button) to force a restart. Repeat this for 3-4 times. When Windows detects multiple startup failure, it will automatically boot into Windows RE.

In Windows Recovery, navigate to Troubleshoot > Advanced options > Command prompt, as shown in the screenshot below. Go to step 2 when you have access to the command prompt.

Step 2: Run Boot Configuration Data Edit command

Corrupted or misconfigured boot configuration data (BCD) is a common cause to the BAD_SYSTEM_CONFIG_INFO blue screen error in Windows 10. This configuration holds data such as how many processors Windows is allowed to use for boot, and the amount of memory to be used during boot.

We will use bcdedit command to set the number of processors and amount of memory allowed to its default value. In the command prompt, enter the following commands. Press the Enter key after each line of command.

bcdedit/deletevalue {default} numproc
bcdedit/deletevalue {default} truncatememory

Bad System Config Info Windows 10 Fix

When you’ve done entering the commands, restart your computer and verify if the Bad system config info Windows 10 blue screen error still persists.

Step 3: Restore Registry files from backup

The BAD_SYSTEM_CONFIG_INFO Windows 10 error could also be due to corrupted registry settings. If you have recently installed software relates to Windows settings, or that you directly made changes to the registry, it could cause blue screen errors such as Bad system config info BSOD.

So, what we going to do now is to copy the Registry Backup created by Windows 10 (Windows will create registry backup occasionally) and paste it to the Registry folder to replace the broken registry.

In the command prompt you’ve opened in Step 1, enter the following commands in order. Hit Enter key after each line of commands.

c:
cd \windows\system32\config
MD Backup
copy *.* backup
CD regback
copy *.* ..
A
exit

Registry fix BAD_SYSTEM_CONFIG_INFO Windows 10 BSOD

To summarize what you’ve just entered, the commands “MD backup” and “copy backup” are to create a backup of the current registry files. Whereas the “CD regback” and copy commands are to copy the registry backup files from Regback directory and paste it to the current registry folder to replace the broken registry. Pressing “A” is to agree the overwrite of the pasting.

When you’ve entered all the commands successfully, restart your computer and see if the issue still exists.

What else can you do?

Blue screen error doesn’t just happen randomly. There must be an unexpected change made in Windows 10 that triggers the BAD_SYSTEM_CONFIG_INFO Windows 10 BSOD. You will have to figure out what you did recently that might cause the issue.

In the meanwhile, you can try to boot into safe mode and remove things you suspect are causing the blue screen error. To boot into safe mode, in the Windows Recovery (we have taught how to force your PC enter Windows Recovery mode earlier), go to Troubleshoot > Advanced options > Startup Settings. Select 4 to boot your Windows 10 into safe mode on next reboot.

If nothing else works, you can try to system restore Windows 10 to an earlier date, or reset Windows 10 without losing your files.
