Why does my PC need repairing?? I don’t understand. I just bought my laptop a month back and it said it needed to update and then suddenly this happens?? What does it mean when it says boot configuration data file is missing some important information and what can I do to solve this issue?

@ashikin77 that means that your system cannot read some of the information required to boot up. You somehow got a corrupted file. You can try to repair this. Since I am not sure which OS you have, you do want to check the answers on here as well as here. Different systems same idea to repair it.
