This program is used to create Microsoft compatible boot records. It is able to do the same as Microsoft "fdisk /mbr" to a hard disk. It is also able to do the same as Microsoft "sys d:" to a floppy or FAT partition except that it does not copy any system files, only the boot record is written. It is useful when using Linux to restore a backup of a reference Microsoft Windows installation. (Excellent for creating bootable Windows 7 install USB).
