  • Damaged I/O ports.
  • Malfunction of external hardware or PC components.
  • Improperly seated components such as a disconnected hard drive that is not making contact with the motherboard.

Reboot your computer

The first and foremost step before trying hard core solutions is to hard reset the computer by holding down the power button until your computer shuts off. Then turn it back on.

This generally solves the blue screen 0xc00000e, but you can continue to next step if the issue goes on.

Scan Windows for Errors or Run a disk check

Make sure your computer hard disk works properly. Here’s how you can go for it:

  • Boot your computer into Safe Mode.
  • Fire up the Command Prompt as administrator.
  • In-there, type ( chkdsk /f /r ).
  • Tap Enter.
  • Press Y on your keyboard.

This will start Disk check the next time you boot your PC. It might take a while. You may want to skip or schedule it if you don’t have time to wait.

Disconnect all external devices

External ( peripheral devices ) such as USB devices, external hard drives can cause an interference with the boot process – at times. Therefore, trying removing these can help you figure out which device is at fault.

Change your BIOS settings

  • Dive into BIOS setup utility.
  • Go to Boot options.
  • Once you are there make sure that the first boot device is your hard drive. To do so: you can press the arrow key to highlight the hard drive and move it to the top of the boot device list.
  • Save and exit the screen.

This will fix Error code 0xc00000e9.

Update your drivers

Error 0xc00000e9 might also appear because of the faulty drivers. If something’s wrong then the hardware can’t communicate with the software – at all.

Make sure that you have the latest drivers installed on your PC and update the ones that are aren’t.

Now, restart your computer and check if Error code 0xc00000e9 persists.

Fix the MBR with Windows PE

MBR (Maser Boot Record) contains the data necessary for loading Windows. It instructs the Windows which drive or partition to use during the boot process. Hence, repairing MBR can help solve Error code 0xc00000e9.

Because if you don’t – Error 0xc00000e9 can pop-up when you install Windows without setting the MBR. Therefore, set your C drive as the MBR to fix Windows Error Code 0xc00000e9.

But, this require some technical computer skills. If you’re ready go for it.

  • Connect the hard drive or any external one with the Windows PE to your PC.
  • Open up Windows PE.
  • In there, set your drive ( C ) as MBR.
  • Now, reboot the system.

This should solve Error code 0xc00000e9.

If the 0xc00000e9 error still persists, continue troubleshooting.

Check for component failures

Check for loose connections for any external devices. If there is something that you can not fix, try contacting the manufacturer for help.

Perform a Clean Install of Windows

This is a powerful solution to fix Windows Error code 0xc00000e9. All the changes made to your system will be overwritten, restoring the system in proper working order.

Perform a System Restore

Often, installing a new device or program can show up Error code 0xc00000e9. System Restore can roll back in the OS to a previous state, reverting the old settings.

Change the Boot Order

Installation of a new hard drive, or external hard drive or a USB device can change the boot sequence or order. Sometimes, updating the system BIOS can trigger up this error.
Therefore, access your computer BIOS or UEFI settings to make sure the hard drive Windows installed is listed at the top of the boot sequence.

Test your Hard Drives

Run your hard drive for a test using the free hard drive testing tools available out there. Alternatively, replace your computer hard drive with the one working.

Perform a Windows Startup Repair

If still you are unable to log in to Windows, then using a Windows disc or a prepared USB drive that includes the Windows automatic repair tools might seem to be a good solution. This startup repair can possibly fix the corrupt system files, registry errors, and missing content, hence fixing Error code 0xc00000e9.

Scan for Malware

Viruses can prevent Windows from booting. So, using a bootable antivirus tool can be a solution. Much better is to download an antivirus program for Windows on another machine and copy it to a bootable drive.

Nearly all virus tools come with a bootable rescue tool that enables you to scan your PC from a command prompt.

Update the volume boot code to use BOOTMGR

This is important. The volume boot code can become corrupt or accidentally reprogrammed to use the wrong boot manager. In-fact it can be associated with a boot loader apart from the conventional Windows BOOTMGR ( Windows Boot Manager ). So, updating the volume boot code should get over with Error Code 0xc00000e9.

If the error is still there, try trouble shooting.

Disable Windows Secure Boot

Windows Secure Boot could prevent external hardware or software from working on with your PC. Disabling it for some time can likely fix the problem.

Rebuild Windows BCD

Broken BCD can also be the reason for 0xc00000e9 error. You have to repair or rebuild Windows BCD. To do so:

  • You need a Windows Installation Media.
  • Few Commands.

Here’s the process.

Boot from the media to recovery mode. Then launch Command Prompt. Now, key in the following commands:

bootrec.exe /FixMbr
bootrec /fixboot
bootrec /scanos
bootrec /rebuildbcd

Note: This process wipes all the data on your system drive. Be Aware!

Checking drives and Windows installation

We c an get into safe mode to perform disk check procedure and Windows files integrity check.

To do so:

  • Launch Command Prompt as administrator.
  • Then enter these commands:
chckdsk /f /r

This will start the disk checking procedure. It will also fix some minor issues on your drives that may prompt 0xc00000e9. Now, wait for the report. If this command returns no error and the system does not boot – check for the system files integrity by this command:

sfc /scannow /offbootdir=X: /offwindir=X:\windows

Now, simply replace the letter X with that of your system drive. For e.g. ( C ).

Hope that solves Windows Error code 0xc00000e9.
