Boot into the recovery environment and run the bootrec/rebuildbcd command.ExplanationThis error message is generated when the system cannot find the partition specified in the BCD database where the operating system files are located. For example, the database might be pointing to the C: drive for the operating system files, but that drive does not exist. To fix this problem, boot into the recovery environment and then run the bootrec/rebuildbcd command to rebuild the boot loader database with a list of valid operating system locations.You will not be able to boot into Safe Mode because the operating system files have not yet been loaded. The fixmbr and bootcfg commands were used on older versions of Windows.
