If you did not backup the data folder, you are in big trouble. Even if the uninstall does not remove any data, since MySQL 5.x the default engine of MySQL is INNODB and INNODB does not store databases and tables in folders and files (as MYISAM did in previous MySQL Releases), but it holds all databases and tables in a single file called "ibdata1".

With the installation of a new release, "ibdata1" will be overwritten by a new (empty) file.

If you have backuped your data folder, you can simply restore it to the current data folder.
