Copying MySQL Raw Data Files for Master-Slave Replication and GTIDs
OBSERVATION #1

The slave needs log-slave-updates in my.ini

OBSERVATION #2

Both Master and Slave need binlog_gtid_simple_recovery in my.ini

MySQL Restart is required on both Master and Slave to include new options

SUGGESTION

Since DB is 5GB, just mysqldump the database on the Master. No need for raw copying

STEP 01 : On the Master, run this

RESET MASTER;
GRANT REPLICATION CLIENT,REPLICATION_SLAVE ON *.*
TO replicator@'%' IDENTIFIED BY 'repl1cat0r';


STEP 02 : On the Slave, run this

STOP SLAVE;
CHANGE MASTER TO
    MASTER_HOST='IP Address of Master',
    MASTER_PORT=3306,
    MASTER_USER='replicator',
    MASTER_PASSWORD='repl1cat0r',
    MASTER_HEARTBEAT_PERIOD=1,
    MASTER_AUTO_POSITION=1
;


STEP 03 : Dump the data on the Master

set mysql_user=root
set mysql_conn=-u%mysql_user% -p
set dump_options=--routines --triggers --events -A --apply-slave-statements
mysqldump -uroot -p %dump_options% &gt; C:\mysqldata.sql


STEP 04 : Copy the dump to the Slave (leave dump in C:)

STEP 05 : Load dump into the Slave

mysql %mysql_conn% &lt; C:\mysqldata.sql


STEP 06: Verify replication

Login to mysql on the Slave and run `SHOW SLAVE STATUS\G`


Give it  a Try !!!
