When Oracle starts, it first reads the "init" file from the Oracle_home/dbs directory (if your server O/S is UNIX or Linux) or the ORACLE_HOME/database directory if your server O/S is Windows.  This "init" file is either the older-style, plain text file with a name like: "init[SID].ora" or the newer (partly binary) spfile, with a name like: "spfile[SID].ora".  You can actually open and read (all except the first and last line of) the spfile with text editor also, just make sure that you *DO NOT* save an spfile from a text editor!  Either of these files will contain a "controlfile" parameter that lists the directory/ies and name(s) of your database controlfiles.  If this entry points to an invalid or incorrect directory path, you will get this error.

You can edit an init file directory with a text editor to correct the name or location of the controlfiles, if necessary, then try starting Oracle again.
