You will then receive an error message which says, The Boot Configuration Data for your PC is missing or contains errors, Error code 0xc0000185. Sometimes, you may get some other error message such as “The operating system could not be loaded because a required file is missing or contains errors. Whatever message you get, this implies a single technical issue.
The solution can be broadly divided into 5 methods. These are:
