Fix: Boot Configuration Data File Error 0xc0000034

A few users reported an annoying problem with their computer or notebook. Instead of booting into Windows, those mentioned computers run into a cryptic failure and instead of greeting the user with the users desktop, those computers only display error boot configuration data file is missing some required information error code “0xc0000034”

Unfortunately there is no option given to fix this issue and also no user friendly explanation on what to do next or even what this error actually means and why it is happening. You need to know that your computer, no matter what Operating System is installed, consists of different parts. There is the motherboard, the processor, memory, power supply and also the hard disk. All those need to work together and something needs to tell what to do. The second you start your computer and power it on you start a small part on the motherboard which acts like a supervisor of all the other parts in your computer. If you want to start Windows 10, this motherboard supervisor needs to know where Windows 10 is located and what file needs to be executed. This information is usually generated while installing Windows onto your hard drive. If this information gets lost however, the computer is unable to start Windows and will show you a error message, similar to the one above. In short, your computer does not know where your Windows is located and is unable to find it. In this guide I will show you how to bring back your computer into a working state.
