Windows 10 Bcd Repair

The Boot Manager in modern Windows versions uses the BCD (Boot Configuration Data) file to boot the operating system installed on the computer. This file contains information about the installed OS and boot parameters. Windows cannot boot normally if the BCD file is deleted or corrupted. Also, you won’t be able to boot your Windows if the Mater Boot Record (MBR) on the hard disk is damaged. In this article, we will show how to correctly rebuild Windows Boot Manager, BCD configuration file, and fix MBR on Windows 10 and 11.

Users have reported receiving the following error message when trying to boot their computers in Windows 10 with the boot configuration data error code 0xc0000454.

Unable To Update Boot Configuration Data

The BIOS (CMOS) setup settings should be entered. Ensure Legacy support is enabled. 3. Change Boot Mode from UEFI to Legacy (CSM). 4. Disable Secure Boot in the Security options. Set the Legacy Windows USB drive as the first boot device. 5. Save the BIOS settings and exit them. 8. Install Windows 10 from the Legacy USB drive.

Windows Booting Files

This is a plain text file that contains installation settings for the InstallShield program, an application that creates setup files to install software. It ends with the .BOOT suffix.

When your PC starts, the boot manager detects a problem with the boot configuration data. Errors occur when the boot configuration data is missing or contains errors. A restart can resolve this problem if the NVRAM resources are not sufficient. The error code 0xc0000454 (STATUS_INSUFFICIENT_NVRAM_RESOURCES) is displayed when not enough NVRAM resources are available to complete an API operation.

You have an error or a missing boot configuration on your PC.”

I have been experiencing some issues with my win10 laptop lately. First of all when installing the lastest driver it wouldn’t recognize my GTX 1060. Also tried getting the last w10 update but it had also some issues and I couldn’t update (from 14xxx build to 15xxx). Tired from everything tried to Reset my PC but then also started getting errors and was unsuccessful on doing so. Finally, last night tried doing a clean install, everything seemed normal but when it completed the installation instead of taking me to the first steps of w10 it gave me “error 0xc0000454”. Trying troubleshooting but it was of no help, tried switching booting options from the BIOS and keep getting the same error. If I did nothing when the error screen came up after some seconds the PC would restart and let me log in. I’m still worried about the error and I don’t know if all this is normal because of the new w10 build.

When your operating system’s BCD cannot be read or accessed, nonvolatile random-access memory (NVRAM) is responsible. If rebooting does not solve the problem, try other solutions.

In this post by Techquack, we will show you how to fix the “missing boot configuration file” error in Windows 10.
