[Koha] Koha database recovery from crashed disk

[Mpore Nshuti Evelyne]

My client's server hard disk crashed. They had not made any backups
since the use of Koha ILS. So my option was to recover database from
MySQL database files (copy from old to new installation). But the
problem i am having is that on loading the staff client interface, the
web installation restarts and after selecting defaults, i get a
Software Error like this:
DBIx::Class::Storage::DBI::_dbh_execute(): Table
'koha_library.search_field' doesn't exist at
/usr/share/koha/lib/Koha/Objects.pm line 110.

I really need help.
