BCD Troubleshooting
Troubles Opening BCD Files
Microsoft Registry Editor Removed
When you double-click your BCD file, you may see a dialog box from your operating system stating that it "Cannot Open This File Type". When this happens, it is commonly due to Microsoft Registry Editor missing in %%os%%. You won't be able to double-click to open your BCD because your OS doesn't know what to do with it.
Tip: When another BCD application is installed, you can choose to open it by selecting "Show Apps" and using that program.
Incorrect Microsoft Registry Editor Version
In some cases, you might have a newer (or older) version of a Windows Boot Configuration Data File file that is unsupported by your installed application version. Installing the latest version of Microsoft Registry Editor from Microsoft Corporation is recommended. This problem is predominately due to having a Windows Boot Configuration Data File file version that was created by a newer version of Microsoft Registry Editor than what you have installed on your PC.
Tip: Investigate your BCD file by right-clicking and selecting "Properties" to find clues on what version you need.
Primarily, problems experienced when opening BCD files are due to having the incorrect version of Microsoft Registry Editor installed on your computer.
Other Causes of BCD File Opening Problems
In the majority of cases, installing the right version of Microsoft Registry Editor will resolve your issue. There can be external issues inside of %%os%% that are causing these errors when opening BCDs. Other contributing causes:
- Invalid BCD file references in the Windows Registry (the "phonebook" of the Windows Operating System)
- Mistaken removal of the Windows registry BCD description
- Partial installation of Microsoft Registry Editor that did not fully complete
- Something has caused file corruption of your BCD
- BCD file integrity has been compromised by malware
- Hardware related to BCDs has device driver corruption
- Your computer does not have the adequate system resources to open the Windows Boot Configuration Data File format
