Many users have complained about Windows 10 boot configuration data error code 0xc0000454, reporting that the problem occurred after they tried to boot the computer. They mentioned that they encountered the following error message:
“Your PC’s boot configuration data is missing or contains errors.”
When you see this error message, it means that the Windows Boot Manager cannot work properly due to a problem with the boot configuration data (BCD). Also, note that error code 0xc0000454 indicates insufficient NVRAM resources to complete the API.
Nonvolatile random-access memory or NVRAM is the component responsible for storing the operating system’s BCD. In most cases, this problem can be solved by simply rebooting the system. However, if rebooting does not solve the problem, you can try other solutions.
