Before getting started with the methods to fix "bcdboot failure when attempting to copy boot files gpt," it's essential to first understand the reasons behind this frustrating issue.

The "failure when attempting to copy boot files" error usually occurs when the system partition is set as inactive. If you are trying to copy boot files to multiple computers simultaneously, it's crucial to ensure that the system partition is active; otherwise, you will encounter this error message when using the bcdboot command.

Although there is a slight chance that the error might be due to corrupt boot files, don't worry; we'll also cover how to handle that situation. Now let's explore the methods to fix this problem and get your computer running smoothly again.

Here are the 3 ultimate solutions for the "failure when attempting to copy boot files" error.

Method 1. Set the System Partition As Active

The most common reason behind "failure when attempting to copy boot files" could be an inactive system partition. So, here are the steps that you can follow and activate your system partition to get rid of this issue.

  • Insert a bootable USB flash drive into your laptop or desktop and restart. Once you see the logo, you will have to simultaneously press F2 or F12 to enter boot mode.
  • Once you are in the Boot mode, select the USB flash drive and hit the enter button.
  • On the Windows Setup window, click "Repair your computer." After that, go to the Troubleshoot option and select "Advanced Options."

So that's how you will be able to activate the system partition and get rid of the "failure when attempting to copy boot files Windows 10" issue.

Method 2. Rebuild MBR

If activating the system partition didn't resolve the issue, you can try rebuilding the Master Boot Record (MBR). The Master Boot Record (MBR) is a crucial part of the boot process as it contains information about the partitions on your hard drive and how to load the operating system.

When the MBR gets corrupted or damaged, it can result in startup problems and prevent boot files from being copied correctly.

That is why it's important to try rebuilding MBR when you are facing "failure when attempting to copy boot files Windows 11" issue.

Here is how you can do that.

  • First of all, insert the Windows installation disc or bootable USB into your computer. After that, restart your computer and access the boot menu or BIOS settings by continuously pressing the designated key like F2 or F12 during startup.
  • Now select the Windows installation disc or USB as the primary boot device and hit enter button.
  • After that, click on "Repair your computer" and then select "Troubleshoot."
  • Now go for "Advanced options" and then click on "Command Prompt."

  • In the Command Prompt window, type the following commands one by one and press Enter after each:

    bootrec /fixmbr

    bootrec /fixboot

    bootrec /scanos

    bootrec /rebuildbcd

  • After executing these commands, restart your computer.

bcdboot c:\windows /s s: /f ALL

The inclusion of "ALL" at the end of the command ensures that both UEFI and BIOS files are copied appropriately.

This process will help ensure that your computer's firmware is updated and compatible with the boot files, potentially resolving the error and allowing your system to boot smoothly again.
