Windows 11: How to Fix Error Code 0xc0000001

What Is 0xc0000001 Error Code in Windows 11?

Windows 11 has its fair share of errors and BSODs. That said, if you’re getting the error code 0xc0000001 as soon as your PC boots up, it may be due to one of the following reasons:

• Your system’s booting files are missing or corrupt.
• The Master Boot Record (MBR) files on your Windows 11 system are corrupt.
• There’s an issue with the installed disk on your system.
• You have installed a buggy Windows Update.

Basic Fixes

• Disconnect connected devices: Remove all the connected peripherals from your PC/laptop and try powering it on.
• Uninstall the recent Windows Update: Press the Windows + I shortcut to open Settings, select Windows Update from the left sidebar, and click Update history. Scroll down, select Uninstall updates, and click Uninstall next to the recent system update to roll it back.
• Perform a clean boot: An installed software may create system conflicts, resulting in the 0xc0000001 error. Clean boot your Windows 11 system and uninstall all the unnecessary applications.
