A lot of people rely on computers to perform their everyday tasks and the least bit of inconvenience can be frustrating especially when you encounter problems during startup.

Unfortunately, you cannot always predict when a Windows error will occur and when it does, you will need to be adequately prepared to handle it.

A BCD error is one of the most frequent Windows errors that can prevent you from booting your device and needs to be fixed immediately.  

Boot Configuration Data (BCD) is a component that helps you to boot your Windows device. When the BCD goes missing or corrupt, you won’t be able to access your computer or hard disk drive and might get stuck on the loading screen.

A BCD error may occur because of several reasons but the most common one is the failure of the hard disk drive or wrong installation of a program.

An unexpected shutdown, malicious software, and the Blue Screen of Death  (BSOD)  are also leading causes of the BCD error.

Is the BCD error related to the BSOD error?

The BCD error can be linked to the BSOD error since it also causes the device to crash. When a Blue Screen of Death occurs in Windows 11, the computer can sometimes fail to boot. The failure to boot can be caused by a variety of reasons. BSOD ERROR

The BSOD error can also prevent you from accessing your system as it undergoes a continuous loop of crashing and restarting. Fortunately, you can also fix your Blue Screen if it is stuck and keeps restarting.

Does a BCD rebuild delete files?

It is not uncommon to be worried that a boot can lead to the loss of important files. However, when you perform a BCD rebuild using any of the BCD commands, you are only repairing the boot files. and all your files will remain intact.

The repair helps does not in any way affect your personal files but rather helps you gain access since the BCD error prevented your device from starting.
