What does bootrec /fixmbr do during Windows startup repair?
The bootrec /fixmbr command repairs the Master Boot Record (MBR) on your system drive without affecting current partitions or personal data. The Boot MBR holds vital Windows startup information that is read when your PC boots. When the MBR is compromised by malware, disk corruption or partitioning changes, your computer will likely not start correctly. bootrec /fixmbr creates a pure Windows-style boot record and removes corrupted startup code. It is often run in conjunction with bootrec/fixboot or bootrec/rebuildbcd to repair Windows startup and fix serious startup errors.
