As Microsoft bluntly puts it, error 0xc0000225 can be related to drivers, OS, or third parties. While we cannot argue with this perfectly valid information, we feel a bit of context is required in order to understand why this happens and what can be done to fix it.

First of all, error 0xc0000225 is a BSoD that will prevent your PC from booting, whether we’re talking about Windows 10 or more recently, Windows 11 and it generally occurs after an unsuccessful upgrade or update attempt.

Here are more potential causes:

  • BCD sys files (Boot Configuration Data) corruption
  • Incomplete/failed/pending update files (This usually happens when the PC shutdowns during the installation of a Windows update and leads to an incomplete setup due to missing update files)
  • Disk errors (Frequently when using the third-party partition manager from EaseUS or when cloning/resizing the hard disk of your operating system)
  • Malware or virus infection affecting system files
  • Faulty hardware, unsigned drivers, or programs recently installed (Windows cannot verify the digital signature)

Now, the error code usually appears after you try to reboot your Windows 10 or Windows 11 PC. And alongside the error code 0xc000025, you will get the message Your PC needs to be repaired.

The given options are Press Enter to try again, Press F8 for startup settings, and Press Esc for UEFI firmware settings. Sadly, none of them works as intended.

Most common scenarios accompanying the error code 0xc0000225:

  • Windows failed to start. A recent hardware or software change might be the cause 0xc0000225
  • The operating system couldn’t be loaded because a critical system driver is missing or contains errors
  • The boot selection failed because a required device is inaccessible (This variation is also possible: A required device isn’t connected or can’t be accessed. Error code: 0xc0000225)
  • The operating system couldn’t be loaded because the system registry file is missing or contains errors
  • Your PC needs to be repaired. Error code: 0xc0000225
  • The operating system couldn’t be loaded because the digital signature of a file couldn’t be verified. Error code: 0xc0000225
  • Windows 11 not booting because of windows\system32\winload.efi with 0xc0000225 error

4. Use diskpart tool

  1. Start Command Prompt as we showed you in the previous solution.

6. Check the boot order in BIOS

If you’re unable to boot to Windows 10 due to error 0xc000025, the problem might be your boot order. To fix that, you need to enter your BIOS and check if your hard drive is set as the first boot device.

Many users reported that this problem occurred because they set the wrong hard drive as the boot device. To see how to enter BIOS and how to change the boot order, be sure to check your motherboard manual for instructions.

Expert Tip: Some PC issues are hard to tackle, especially when it comes to corrupted repositories or missing Windows files. If you are having troubles fixing an error, your system may be partially broken. We recommend installing Restoro, a tool that will scan your machine and identify what the fault is.

Sometimes error 0xc000025 can occur if your BIOS is out of date. To fix that problem, you might want to try updating your BIOS.

We have to warn you that BIOS update is an advanced procedure, so be extra cautious while updating your BIOS. BIOS updates can cause permanent damage to your PC, so keep in mind that you’re updating BIOS at your own risk.

To see how to properly update your BIOS, be sure to check your motherboard manual and follow the instructions carefully. If you need more information, you might want to check our article on how to flash your BIOS.

9. Check your hardware

If this error still appears on your PC, the problem might be your hardware. Several users reported that this problem occurred because their RAM modules were faulty.

To see if your RAM is the problem, you need to test your RAM modules one by one. The best way to do that is to use the MemTest86+ tool or the newer AIDA64 Extreme.

In order to perform a detailed scan, it’s advised to run the scan for a couple of hours.

Keep in mind that you’ll need to scan all your RAM modules one by one or in groups if you want to find the faulty module.

Other hardware can also cause this problem, and a few users reported that their issue was caused due to loose cables. According to them, their hard drive wasn’t properly connected, and that caused the issue to appear.

If you’re having the same problem, be sure to check if your cables are tightly connected.
