How to Fix BCDedit.exe Errors Without Downloading Software

You can fix bcdedit.exe errors using built-in Windows tools. These errors usually happen due to a corrupted Boot Configuration Data (BCD) file or missing system files.

Method 1: Rebuild the BCD via Advanced Startup

Step 1: Access Command Prompt

Boot your PC using a Windows installation USB, or force restart three times to enter Advanced Startup.
Click Troubleshoot.
Select Advanced options.
Choose Command Prompt.

Step 2: Run Repair Commands

Type the following commands into the Command Prompt one by one, pressing Enter after each:

bootrec /fixmbr
bootrec /fixboot
bootrec /scanos
bootrec /rebuildbcd

Note: If bootrec /fixboot gives an "Access is denied" error, run bootsect /nt60 sys first, then try again.

Method 2: Run SFC and DISM Tools

If Windows boots but bcdedit.exe throws errors inside the OS, system files might be corrupted.

Open the Start menu, type cmd, right-click Command Prompt, and select Run as administrator.
Type this command to scan and repair system files:
```
sfc /scannow
```
Wait for the scan to finish.
Next, type this command to repair the Windows system image:
```
DISM /Online /Cleanup-Image /RestoreHealth
```
Restart your computer.

Method 3: Reset the BCD Store

If the BCD store is corrupted beyond simple repair, you can delete it and let Windows recreate it from scratch.

Open Command Prompt from the Advanced Startup menu (see Method 1).

Type the following commands to back up and delete the old BCD file:

bcdedit /export C:\BCD Backup
c:
cd boot
attrib bcd -s -h -r
ren c:\boot\bcd bcd.old

Rebuild the fresh BCD file:
```
bootrec /rebuildbcd
```
Type Y (Yes) when asked to add the installation to the boot list.
Exit and restart your PC.
