The dash is important -- tells file(1) to read from stdin.  Example:

_[/root]_(root at atom)_
# file - < /dev/sda
/dev/stdin: x86 boot sector; GRand Unified Bootloader, stage1 version 
0x3, boot drive 0x80, 1st sector stage2 0x138800, GRUB version 0.94; 
partition 1: ID=0x83, active, starthead 32, startsector 2048, 1572864 
sectors; partition 2: ID=0x82, starthead 8, startsector 1574912, 1048576 
sectors; partition 3: ID=0x83, starthead 77, startsector 2623488, 
56002560 sectors, code offset 0x48

Take a look at grub2-install or grub-install, depending on what you have 
installed.
