Question:

I’ve assembled a new computer, but I encounter an issue where it initiates the boot process only to shut down after a few seconds. Upon accessing the Windows Recovery Environment, I received the error code 0xc0000225, indicating a problem with the Windows files. Consequently, I prepared a bootable USB with Windows 10. However, when I reach the USB boot screen, both my keyboard and mouse cease to function, preventing any interaction. They remain connected and functional until this point but fail to respond past the USB boot screen. The BIOS settings appear correct, and all components seem well-connected. Could you provide guidance on resolving this boot issue from the USB? Your expertise would be invaluable. Thank you. (Apologies for any confusion; English is not my first language.)”

Answer:

Building your own PC can be a rewarding experience, but it can also come with its own set of challenges, particularly when it comes to booting the system for the first time. The issue you’re facing, where the computer starts to boot and then shuts down, followed by difficulties in booting from a USB drive, is not uncommon. Let’s address the problem step by step.

The error code 0xc0000225 that you encountered in the Windows Recovery Environment is typically related to a corrupted Boot Configuration Data (BCD) file. This file is essential for Windows to start up properly. The corruption can occur due to various reasons, including abrupt shutdowns, disk write errors, or incompatible installations.

Troubleshooting Steps

1.

Repairing the BCD

: Since you have access to the Windows Recovery Environment, you can attempt to repair the BCD using the command prompt. The commands `bootrec /fixmbr`, `bootrec /fixboot`, and `bootrec /rebuildbcd` can be helpful in fixing the issue.

2.

Ensuring Secure Boot and Legacy Mode Settings

: Check your BIOS settings to ensure that Secure Boot is disabled and Legacy Mode is enabled. These settings can sometimes interfere with the booting from a USB drive.

3.

Checking USB Ports and Devices

: If your keyboard and mouse stop working at the USB boot screen, it could be due to a USB port issue. Try connecting them to different USB ports, preferably USB 2.0 ports, which are more likely to be recognized during the boot process.

4.

Updating BIOS

: An outdated BIOS can cause compatibility issues with newer hardware and software. If possible, update your BIOS to the latest version provided by your motherboard manufacturer.

5.

Testing Hardware Components

: Since this is a newly assembled PC, there’s a possibility of hardware incompatibility or failure. Test your RAM, hard drive, and other components to ensure they are functioning correctly.

6.

Creating a New Bootable USB

: The USB drive itself might be the issue. Try creating a new bootable USB using a different tool or method, and ensure that it’s formatted correctly (usually as FAT32 for UEFI systems).

Final Thoughts

If these steps do not resolve the issue, it may be worth considering professional assistance or reaching out to online forums for further guidance. Remember, building and troubleshooting a PC requires patience and sometimes a bit of trial and error. Good luck!
