A step-by-step guide to fix error code 0xc000009

As soon as you identify the error’s root cause, you may start the real troubleshooting procedure. There are several options available. You may try each one separately to make the issue go away.

Disconnect all the peripherals

As we previously mentioned, one of the most frequent causes of the Windows boot bcd error is an incompatible or malfunctioning hard drive. As a result, we recommend turning off your computer, unplugging all peripherals and external devices, including your wireless mouse, USB drive, external hard drive, keyboard, and so on, and restarting your computer.

You can re-insert your peripherals and external devices one at a time if the issue stops occurring. Then, you’ll be able to identify the offending gadget. After locating the defective device, you have two options: replace it with a working one or update its driver to the most recent iteration advised by the manufacturer.

Check your issue with the hard drive

The error code 0xc00000e9 will show up in Windows 10/8/7 if the disc has certain problems or faulty sectors. Therefore, it is strongly advised that you check the disc for errors.

  • Start your computer, put in the Windows installation DVD, and restart it.
  • After choosing your language and area, click Repair your computer.
  • Choose “Troubleshoot” > “Command Prompt” from the installation disc for Windows 10 (or Windows 8.1, Windows 8). Select Windows 7 as the operating system and the first option under System “Recovery Options” on a Windows 7 installation disc, then click “Next” > “Command Prompt”.
  • Enter “chkdsk /f /r” in the Command Prompt window.
  • On your keyboard, hit Y.

Check the system files

In the Command Prompt window that you open in the last method, you can also input “sfc /scannow /offbootdir=d:\ /offwindir=d:\windows” to check the integrity of Windows file systems.

Repair your Windows BCD files

The bootloader configuration (BCD) repair may be useful in some circumstances. You must restart the computer after executing the below instructions in the Command Prompt window to do:

bootrec.exe /fixmbr

bootrec /fixboot

bootrec /scanos

bootrec /rebuildbcd
