recover partitioned table (no replies)

Environment: RHL 7, MySQL 5.7.15

What happened:
Accidentally deleted all the .idb files of a partitioned table. The database did not start up on restart.

Add "innodb-force-recovery=1" to my.cnf, database started, verified the partitioned table does not exist by checking the information_schema.tables, information_schema.partitions, and by "desc" command and by "select" statement.

Then I remove the "innodb-force-recovery=1" from my.cnf, and restarted the database.

Now my problem is,
I can recreate the table as a regular table, but I cannot recreate it as a partitioned table, nor can I change it to partitioned table after I created it as a regular table.

If I try to recreate it as partitioned table, the error message complains the very first partition already exists;

If I try to change the recreate regular table to partitioned table, the error message complains the table already exists.

Thanks
