Error 0xc0000225 in Windows 10 – Explained and Fixed

The Error 0xc0000225 in Windows 10 is a ‘stop error’ and it usually happens on the Unified Extensible Firmware Interface (UEFI) mode. This error occurs when there are difficulties in the booting path of the operating system, which makes you unable to start your system.

Sometimes, this error code is accompanied by the following error messages:

  • A required device isn’t connected or can’t be accessed
  • The application or operating system couldn’t be loaded because a required file is missing or contains errors
  • The operating system couldn’t be loaded because the digital signature of a file couldn’t be verified

This error is also known as ‘BSoD (Blue Screen of Death)’ and it happens when the Windows package cannot realize the required system files for starting or booting the system.

Here are a few use cases after which users have faced the error 0xc0000225:

  • Modifying the size or cloning the operating system hard disk.
  • The system was accidentally turned off while installing a Windows update.
  • While installing the application or device driver from an unsigned owner (whose digital signature can’t be verified).
  • While upgrading your operating system (either from Windows 7 to Windows 8 or Windows 7 to Windows 10).

What Causes Error 0xc0000225 in Windows 10?

Whether you’re using Windows-8 or Windows-10, this error occurs on both and sometimes on Windows-7 as well. Following are its major causes:

  • When you’re using the UEFI mode which uses GPT (GUID Partition Table) scheme to achieve fast boot over the traditional BIOS mode that uses MBR (Master Boot Record) sectors on the hard disk; your operating system gets confused between these two schemes. This confusion makes the OS unable to find the required system files for booting the system.
  • When you’ve recently installed the device driver or some application with unverified digital signatures and that application or driver results in the corruption of the system files.
  • Hardware fault (but only if all the other causes are crossed out).

After every scenario, users complain about not being able to start their systems. There are several fixes to this issue, but only a few of them works perfectly. So, let’s try those.

How to Fix Error 0xc0000225 in Windows 10?

Since this is an issue with the booting of your system, so before trying the subsequent solutions, you should boot your system from the Windows Installation Media. Because most of the subsequent issues depend on that. However, if you don’t have one, then you can create the Windows installation media via Microsoft’s ‘Media Creation Tool.

Plus, if the following solutions do not fix your problem, then hardware fault is the reason for your issue. Anyway, let’s get to the fixes of this error.

  8. Now pick your System Reserved volume by looking at the ‘Info’ column and choosing the entry that is displaying ‘System’ as its value.

Note: System Reserved volume is usually the volume with the smallest size and if you have a UEFI system, then its ‘Fs’ (File System) will be FAT32

Picking the System Reserved Volume
  1. Once you’ve found the volume number of your system reserved drive, then type ‘select volume 0’ and press the ‘Enter’ key.

Note: Replace the number ‘0’ with your System Reserved drive numbe

Solution 2: Fixing it via Windows 10 Repair Environment Options

(For Windows 10 Users who don’t have the Boot or Repair Disc)

verified solution

You can apply this solution if you’ve faced the ‘UNMOUNTABLE_BOOT_VOLUME’ issue and then your system went into the repair mode, but never recovered and now you’re facing the ‘error 0xc0000225’ in Windows 10.

In the following solution, we will try multiple methods from the Windows 10 Repair Environment. If any of these sub-methods didn’t work for you, then you can try the next solution.

  1. Power on your system and wait for the Manufacturer’s logo to disappear. Once the logo disappears and Windows-10 tries to boot, hold the power button for about 5-10 seconds.

Note: Perform the Step-1 Twice

  1. On the third attempt, Windows-10 should boot into the ‘Windows-10 Repair Environment.
  2. In the repair window, choose the ‘Troubleshoot’ option.

    Choosing the ‘Troubleshoot option’

From here, apply one of the three sub-methods (after following the three steps discussed above).

Checking for A System Restore Point

(For Users Having a Restore Point)

  1. Select ‘Advanced options’ in the ‘Troubleshoot’ window.

    Choosing ‘Advanced options’ in the ‘Troubleshoot’ Window
  2. In the next window, choose the ‘System Restore’ option.

  5. Follow the wizard of System Restore and if the system finds the restore point, then click Yes to initialize the process.

    Clicking ‘Yes’ Upon Finding the Restore Point
  6. Once the system has finished restoring, click the Restart button.

Hopefully, this will resolve the issue. However, if there’s no system restore point or this process didn’t resolve your issue, then follow the rest of the Sub Methods.

Backing Up Data via Safe Mode and Rebooting

  1. In the ‘Advanced options’ window, choose the ‘Startup Settings’ option and click Restart.
    Choosing ‘Startup Settings’ in ‘Advanced options’ Window

    Clicking the ‘Restart’ for restarting in the Safe Mode

If the system boots normally, then the issue has been resolved. Otherwise, follow the next sub method.

Resetting the PC by Keeping All the Files

(For Users who have failed in previous Solutions)

  1. In the ‘Troubleshoot’ window, select the ‘Reset this PC’ option.

    Choosing ‘Reset this PC’ in ‘Troubleshoot’ Window

Solution 3: Resolving the Issue via Fixing the Boot Files

(For Users who can’t get into the Recovery Environment)

verified solution

In this solution, we will again use the Windows-10 Installation Media for booting into the system. However, if you don’t have one, then you can create the Windows installation media via Microsoft’s ‘Media Creation Tool.’

  1. Follow the ‘first 8 steps of Solution 1’ for opening the CMD window via the ‘Repair your computer’ option through Windows-10 setup.
  2. Once you’ve opened the CMD, type the following commands and press ‘Enter’ after each command to let the command prompt execute each command:
bootrec /fixmbr

bootrec /fixboot
bootrec /scanos

bootrec /rebuildbcd
  1. After each command, the CMD will show the following message:
"The operation completed successfully"
  1. After executing all the commands, add the installation to the boot list by pressing the ‘A’
  2. Now close the CMD window and restart your system.

After a successful restart, the ‘error code 0xc0000225’ will resolve. But if that didn’t work and all the above methods didn’t work, then you have a hardware issue.
