One of the most teasing bugs that exist in older versions of Windows, including Windows XP, and in newer versions, including Windows 8, is the 0xc000000f error. This error is connected to the Windows boot manager and when Windows attempts to read boot configuration data, it displays this error message that prompts users to repair their PC from the Windows installation media.


The most common reason for the 0xc000000f error is that BOOTMGR cannot find the BCD file. It may be damaged or missing due to causes such as viruses, power failures, hard disk write errors or user errors when manually setting the BCD. A corrupted file system is also the cause that could cause the 0xc000000f error because during the upgrade process (working on writing critical information for the boot sector) suddenly shuts down, or the update process has jammed and you forced the computer to shut down.

How to correct start error 0xc000000f:

Manual reconstruction of the BCD file


In addition to using the “Startup Repair” function on the installation disc to correct the error, you can also manually recreate the BCD data file.

To do this, follow the same instructions as above to start installing Windows, then select Command Prompt from the options.

In the next step, execute the following command to recreate the BCD on your computer.

bootrec /rebuildbcdd

The system automatically searches for a Windows installation and recreates the BCD file.
