To run the Bootrec.exe tool, you must start Windows RE. To do this, follow these steps:

Bootrec.exe options
The Bootrec.exe tool supports the following options. Use the option that is appropriate for your situation.
/FixMbr
Use this option when you must resolve MBR corruption issues, or when you have to remove non-standard code from the MBR.
/FixBoot
Use this option if one of the following conditions is true:
- The boot sector has been replaced with a non-standard Windows Vista boot sector.
- The boot sector is damaged.
- An earlier Windows operating system has been installed after Windows Vista was installed. In this scenario, the computer starts by using Windows NT Loader (NTLDR) instead of Windows Boot Manager (Bootmgr.exe).

Use this option when you must completely rebuild the BCD.
