Hello Die Katze, Thanks for posting this in our community.
You're encountering the error "The Boot Configuration Data for your PC is missing or contains errors" with status code 0xc000014c while trying to reinstall Windows 11. This usually means the boot files are either missing or corrupted, often due to how the installation media was created.
The safest method is to use the official Windows 11 installation media provided by Microsoft. You can download it from https://www.microsoft.com/en-us/software-download/windows11. Once there, select "Create Windows 11 Installation Media" and follow the instructions to create a bootable USB drive using the Media Creation Tool. This ensures that all necessary boot files are included and avoids compatibility issues that sometimes occur with third-party tools.
After creating the USB, insert it into your PC and boot from it. If your system supports UEFI, make sure Secure Boot is disabled and the boot mode is set to UEFI in your BIOS settings. Once the installer loads, you can proceed with installation or choose "Repair your computer" to fix boot issues.
Hope this works on your device.
Kind regards,
John Oli
