How to Fix Windows Error Code 0xc0000001

Microsoft Windows displays a dreaded blue screen of death error 0xc0000001 for various reasons. These items include faulty hardware devices, problematic system files, suspicious installed apps, faulty system configuration, etc.

However, you can use these solutions to fix the error message from your PC.

Unplug External Devices From Your PC

When you get a blue screen of death with the error code 0xc0000001, a simple fix to apply to potentially resolve the issue is to detach any unnecessary hardware devices from your computer. In most cases, you only need a keyboard and a mouse connected to your PC.

You can remove other devices, like USB drives, Bluetooth adapters, web cameras, printers, and scanners. Once you’ve detached these items from your machine, turn on your PC, and your issue should likely be resolved.

You’ll want to consult your device’s manual and check if the device is compatible with your machine. Otherwise, the device will continue to cause the PC to display an error 0xc0000001.

Use the Windows Startup Repair Tool

Windows has a Startup Repair tool that automatically kicks in when your PC has a startup problem. This tool helps you fix many issues related to your computer’s boot, including the one you’re experiencing.

If you don’t find Startup Repair launching on your PC’s startup, boot your PC from a bootable media drive and launch the tool manually.

1. Boot your PC from a bootable media drive and select Next > Repair your computer.
2. Navigate to Troubleshoot > Advanced options > Startup Repair.

3. Follow the on-screen instructions to fix issues with your PC’s startup.

Remove Problematic Apps From Your PC

A malicious app installed on your PC can cause Windows to return a blue screen of death with an error code 0xc0000001. In this case, your best solution is to remove the app in question from your machine.

Doing so should fix your current issue and prevent any future problems that this malicious app can cause. Since you can’t boot into Windows on your PC, you must use a bootable media drive and enter safe mode to remove the problematic app.

1. Boot your PC from a bootable media drive and select Next > Repair your computer.
2. Choose Troubleshoot > Advanced options > Startup Settings and select Restart.
3. Press the number corresponding to the Enable Safe Mode option on your screen.

Fix MBR and Rebuild BCD

If you continue to get the 0xc0000001 Windows error, your computer’s MBR (Master Boot Record) or BCD (Boot Configuration Data) may not be working correctly. In this case, use the Command Prompt to fix issues with both these tools.

2. Select Troubleshoot > Advanced options > Command Prompt to launch a CMD window.
3. Type the following commands in CMD, pressing Enter after each line:

4. Close Command Prompt and reboot your PC.

Fix Windows’ Corrupted System Files

1. Boot your PC from a bootable drive and choose Next > Repair your computer.
2. Head into Troubleshoot > Advanced options > Command Prompt.
3. Type the following commands in CMD, pressing Enter after each command:
