You try to do a factory reset on your system to restore it to default settings. However, you are greeted with an error “Unable to reset PC. A required drive partition is missing.”
Now, this error occurs due to a corrupt MBR (Master Boot Record) or BCD (Boot Configuration Data) file. One of the other errors associated with this issue is “The drive where Windows is installed is locked. Unlock the drive and try again.” This error is caused when BitLocker boot agent is disabled, TPM (Trusted Platform Module) is cleared or reset, or a damaged BCD file.
Let us explore the solutions to this problem.
