head -b 440 /usr/lib/syslinux/bios/mbr.bin > /dev/sda

  I suspect you meant -c 440; I can’t find a variant of head(1) that has a -b operand on any Unix. Note that -c is not POSIX but does have widespread support. Notably missing on Solaris. Fun fact, the -c usage comes from ksh, where head is a shell builtin.

    Oops, yes, -c indeed! Thanks!
