Save Master Boot Record
File / Save Master Boot Record... / "n"th Harddisk
You may save the entire master boot record (incl. any installed bootmanager) to a binary file (*.bms). This file may later be used to restore the master boot record exactly as it has been saved (e.g., after the bootmanager has been uninstalled). Hereby, not only the MBR, but the entire Track 0 (i.e. the first 63 sectors) will be saved.
The files is saved without any encoding. This means you might want to consider protecting them from any unauthorized access.
