You need to use a force field that supports boron.  Most biomolecular force 
fields won't, and none of the force fields provided in Gromacs recognize boron. 
  Perhaps someone has parametrized boron for a suitable force field, and in that 
case you will have to extend that force field to add boron, then figure out a 
way to generate the topology (probably manually, as servers will clearly not do it).
