This error "Missing operating system" comes from the boot sector; you
can actually look at the boot sector very easily by doing:

  objdump -D -b binary -m i8086 cloned.img

A while back I looked into one of these boot sector disassemblies and
found that the "Missing operating system" error occurs for quite a
specific reason, although I can't quite recall what that was now.
