Solved: Windows Failed to Start File Boot BCD Error

The Error: Windows Failed to Start File Boot BCD

One of my clients says his computer failed to start when he powers up the machine. He gets following prompting message on his screen. He is pretty sure that there is no hardware change before this startup. And he bought that PC for three years and cannot find the Windows installation disc now, let alone to fix the problem as instructed. It seems like contacting manufacturer may not work because he made some changes to the PC a year ago. Then, what can he do to fix the boot BCD error in Windows 10?

Windows failed to start BCD

Searching online, except for “The Boot Configuration Data for your PC is missing or contains errors”, it is not difficult to find that there are other similar errors on boot BCD file and Windows failed to start. For example:

  • Status: 0xcf. Info: An error occurred while attempting to read the boot configuration data.

  • File: \windows\system32\sprers.eu Status: 0xce. Info: The selected entry could not be loaded because the application is missing or corrupt.

  • File: \Boot\BCD. Status: 0xc Info: The Windows Boot Configuration Data file does not contain a valid os.

Some of them account for non system disk or disk error, while some have other causes. Therefore, it is important to figure out what caused the issue and what you can do to fix the issue.

What is Boot BCD file in Windows?

Before learning the causes, you may want to have a brief understanding of the Boot Configurations Data (BCD) file and how it works. Generally speaking, the boot sector loads the Windows Boot Manager (a file named BOOTMBR on either the system or the boot partition), accesses the BCD store and makes use of the information to load the operating system. And then the BCD invokes the boot loader and in turn proceeds to initiate the Windows kernel.

From the definition of BCD on Wikipedia, we can see that the BCD plays an important role during Windows startup. Anything wrong with the file will lead to aforementioned situations and errors. Then, what causes Boot BCD errors?

There are several main possible causes for boot BCD error in Windows 7/8/10/ One is dual boot system on that disk and decides to remove one of them later. The BCD store may have been deleted inadvertently during the remove process. That could happen because of disk write errors, power outages, boot sector viruses, or errors made while configuring the BCD manually.

Simple Fixes for Windows Failed to Start File BCD Error

In a nutshell, you have two kinds of solutions available. If you have a Windows installation disc CD in hand, try the first solution. Several methods of fixing the problem provided. If you have no Windows installation CD, try the second one. It offers the simplest way of repairing MBR and BCD.

Method 1. Fix BCD Error with Windows Installation Disc CD

Boot up your computer via the Windows installation drive. In Windows 7, go Repair your computer > Next > System Recovery Options > Command Prompt. In Windows 10, go Repair your computer > Advanced options > Command Prompt. Alternatively, you can choose Start-up Repair at this step and let it repair automatically. In Windows XP, you need to boot from Windows Recovery Console. In Command Prompt, you can do following attempts to repair.

Scan and Repair MBR: Type following commands in turn and each command come with an Enter.

  • sprers.eu /fixmbr

  • sprers.eu /fixboot

  • sprers.eu /scanos

  • sprers.eu /rebuildbcd

Delete and Rebuild BCD: Type following commands in turn and each command come with an Enter.

  • attrib –r –s –h c: \boot\bcd (unhide BCD file)

  • del c: \boot\bcd (delete the BCD file)

  • bcdboot c: \windows (create a new BCD on C drive)

Tips: You need to restart your machine to make those commands take effect.

Clean the Disk Completely: For the user who wants to perform a clean install to fix “Windows failed to start file boot BCD in Windows 7/8/10” error or for other purposes, it is not bad to delete all data on the disk. Then, create a brand new boot BCD file along with the new operating system. Type following commands:

  • diskpart

  • list disk

  • select disk n (where n is the number of the disk you want to wipe)

  • clean

  • exit

Note: All data on the disk will be wiped, so the system won’t boot after you run clean. Think twice before you leap.

Tips: If you are not familiar with command user interface (CUI), you can wipe hard drive from BIOS using graphical user interface (GUI). Then, you can perform a clean install if you wish.

As mentioned, some users may not get used to command line operations, so GUI repairing is more helpful. In addition, it is also a problem if there is no Windows installation CD around. Don’t worry. Let’s learn how to do boot BCD error Windows 7 fix without CD in the next part.

Description and Symptoms

The error messages, alerts, warnings, and symptoms below are tied to this error.

Symptom 1: 0xcf error screen on startup

As a part of the system startup procedure, the BOOTMGR bootloader first introduced in Windows Vista and used in all later versions of Windows, including Windows 7, Windows 8(.1), and Windows 10, uses a database of entries and configuration options known as the BCD (Boot Configuration Database), which acts as a global store for all boot-related options and settings on newer Windows PCs. However, if the BCD file is not found, then a &#;0xcf&#; error appears and the boot process is halted.

The following is a screenshot of this error as it appears during the Windows Vista and Windows 7 startup:
