Key notes

Computers and laptops are a staple in today’s digitalized world. They are necessary for work, school, and even during our own free time.

We store sensitive data on our PCs, and we can’t afford for it to get lost or their system to get compromised.

Unfortunately, Windows errors are quite frequent, and many can lead to serious problems with the operating system or the PC’s components.

One of them is called the BCD (also known as Boot Configuration Data). As its name suggests, the problem will prevent the system from booting.

Seeing messages likeBOOTMGR is missingor similar during the booting process indicates that there is a problem with the BCD that needs to be solved immediately.

Rebuilding the corrupted Boot Configuration Data isn’t the hardest of tasks if you know where to look. If theBCD is missingor got corrupted, your PC won’t boot into the system.

Why does the corrupted BCD error occur?

This error can happen for various reasons, but it mostly points towards an installation problem (where you’ve probably deleted the BCD) or the possible failure of an HDD drive.

If the latter is the problem, rebuilding BCD won’t do you too much. However, if it occurred due to a software error, or because the data bugged out while it was being read by the PC, rebuilding BCD is the sure fix.

Another cause could be hardware. The data can get corrupt when you change one of your PCs components. These are not all of them. There aremany other BSOD causesout there.

How do I fix corrupt BCD on Windows 10?

1. Rebuild the BCD

1.1. Create a bootable drive

Now, before we move to the rebuilding procedure, let’s prepare all the things you’ll need to fix the BCD in Windows 10. The first thing is a bootable installation drive, which you can create with ease by using Media Creation Tool.

If you’re having trouble with the process, you canfix all issues regarding the bootable USB flash drive.

1.2. Boot with USB

1.3. Rebuild BCD

2. Reset Windows

3.Perform a System Restore

Is the BCD a type of BSOD error?

Yes, it is. Since it technically causes the device to crash before it starts, it is a type of blue screen error. As such, it should be considered problematic and fixed as soon as possible.

Additionally, a BSOD that is tied to the system startup will create a never-ending loop of crashing where your system crashes, tries to restart, and crashes again.

The BCD error could also make thebooting process take too long. You will have to wait minutes instead of seconds, just to enter the Windows Startup.

How can I prevent such errors from occuring?

In order to prevent BSOD errors from occurring, one has to keep his system clean and sheltered from malicious software that can corrupt the data.

Run regular full scans of your OS to make sure it hasn’t been infected by viruses. Here’s how you can do that:

Thankfully, there are plenty of ways to remedy this problem. Simply follow them thoroughly and make sure to enter the correct lines in the CMD window and everything will end up fine.

Obviously, things change all the time, and Microsoft keeps coming up with new updates that introduce new systems, so if you think there is another way to fix this issue, don’t hesitate to tell us.
