Method 1: Checking the Compatibility of your Hardware

As we’ve mentioned, one of the causes of this error can be malfunctioning or incompatible drivers. As such, we recommend disconnecting external devices, such as USB flash drives and external hard drives. However, leave your keyboard and mouse connected. After disconnecting the external devices, restart your computer.

If this method fixes the issue, you can plug back your devices one at a time. Restart your computer after connecting a device. You should be able to determine which of them causes the error. In this case, you would have to update its driver to the latest manufacturer-recommended version. To complete this step, proceed to Method 3.

Method 2: Changing the BIOS Settings

Another method for fixing the 00000e9 error is booting the computer through the hard drive. With that said, here are the steps you should follow:

  1. Turn off your computer.
  2. Boot it by pressing the Power button.
  3. Press the appropriate button to enter the BIOS settings. The key varies depending on the brand of the computer you have. It is best to consult your user manual, but generally, it can be the F12, F2, ESC, or Delete key.
  4. Once you get inside the BIOS Setup Utility, go to Boot Options. Set the hard drive as the primary boot device. Use the arrow key to move it to the top of the list.
  5. Save the changes you made and restart your computer. This should resolve the problem.

Method 3: Updating your Drivers

You can also fix 0xc00000e9 error on Windows 10 and Windows 7 by updating your drivers. In some cases, this issue can be caused by incompatible or outdated drivers. What you can do is go to the manufacturer’s website and search for the latest driver version. However, this can be time-consuming and a bit complicated. You might end up downloading the incorrect version, further damaging your drivers.
