How to Rebuild BCD in Windows 10: A Step-by-Step Guide

Rebuilding the Boot Configuration Data (BCD) in Windows 10 isn’t as daunting as it sounds. It’s like giving your computer’s brain a quick reboot to fix any confusion it might have about loading the operating system. You’ll need to access the Command Prompt in a specific way, use a few commands to clean up the old BCD store, and then create a new one. With these steps, your PC should be back to normal in no time.

Step by Step Tutorial: How to Rebuild BCD in Windows 10

Before diving into the nitty-gritty, it’s important to know that rebuilding the BCD can resolve boot issues preventing Windows from starting properly. Let’s walk through the process.

Step 1: Access Windows Recovery Environment

Restart your computer and press F8, F11, or the designated key for your device to enter the Windows Recovery Environment (WinRE).

Getting into the Windows Recovery Environment is like stepping into a secret workshop where you can fix all sorts of system-related problems. If you’re not sure which key to press, it’s often displayed on your screen right after restarting.

Step 2: Select Troubleshoot

In the WinRE menu, choose ‘Troubleshoot’ to access advanced repair options.

Think of ‘Troubleshoot’ as your toolbox. This is where you’ll find everything you need to get your system back into tip-top shape. It’s a straightforward process where you select options that lead you directly to the Command Prompt.

Step 3: Open Command Prompt

Click on ‘Advanced options’ and then ‘Command Prompt’ to open it.

The Command Prompt is like the control panel of your PC’s operations. Once inside, you’ll have the power to manually input commands that can resolve issues at a deeper level than regular users usually go.

Step 4: Back Up and Delete Existing BCD

In Command Prompt, type bcdedit /export C:BCD_Backup and press Enter to back up the existing BCD, then type attrib C:bootbcd -h -r -s followed by del C:bootbcd.

Backing up first is like saving your game before a big battle. You want to make sure you have a copy just in case things don’t go as planned. Deleting the old BCD clears the way to build a shiny new one.

Step 5: Rebuild the BCD

Type bootrec /rebuildbcd and press Enter to create a new BCD.

This command is where the magic happens. It scans your computer for operating systems and makes sure they’re listed in the BCD, making it possible for your computer to boot up correctly again.

After completing these steps, your computer should recognize the operating system without any boot issues. It’s like giving your computer a map so it knows exactly where to go when starting up.

• Make sure your computer is plugged in to avoid shut down during the process.
• Use a USB recovery drive if you can’t access WinRE.
