MySQL not starting in XAMPP

MySQL may not start if its data files are corrupted.

If MySQL was not shut down properly, it may cause issues on restart.

1) rename xampp\mysql\data => xampp\mysql\data_old

2) create new folder xampp\mysql\data

3) copy everything from xampp\mysql\backup to xampp\mysql\data without ibdata1

4) copy all YOUR (skip mysql) database folders from xampp\mysql\data_old to xampp\mysql\data

5) copy file xampp\mysql\data_old\ibdata1 to xampp\mysql\data\

6) start mysql
