So it's similar to my answer here:

  https://www.redhat.com/archives/libguestfs/2013-November/msg00092.html

what you would do is change /dev/sda (which means the whole disk),
to /dev/sda1 (for the first partition), /dev/sda2 (second partition)
and so on:

  guestfish --ro -a disk.img run : pread-device /dev/sda1 512 0 > mbr.1

If you want to find out what/how many partitions a disk image
contains, use the virt-filesystems program, eg:

  virt-filesystems -a disk.img --partitions

HTH,

Rich.
