How to Backup the BCD Boot File When It Gets Corrupted

Going to your PC to turn it on, only to find out that you can’t actually do so can be an inconvenience at best, and a veritable nightmare scenario at worst. While there may be many reasons why your PC can’t be turned on, one of the most frequent problems that plague PC users is related to the Boot Configuration Data, a.k.a. the BCD.

This crucial piece of code can be corrupted in a variety of ways – your computer getting turned off incorrectly due to a power failure, some system error, in case of a hard drive failure, or even due to a malware attack. All of these may be the cause of the BCD getting corrupted.

In the case of a hardware failure, said component obviously needs to be replaced with a new one. In all other cases, the best course of action is to use a backup copy of the BCD boot file in Windows 10 to replace the corrupted file. Follow the quick guide below to create a backup of this critical file, so that if you end up suffering such a setback, the issue can be resolved quickly and easily.
