I have resolved the problem. First i deleted all my.ini files (in c:\windows and c:\documents and settings\administrator\windows) and my.cnf file (in c:) and created a new my.cnf containing only
[mysqld]
basedir=D:/mysql
datadir=D:/mysql/data
And to be sure i copied the file to c:\windows and renamed it to my.ini
then i opened the console, changed to d:\mysql\bin and started mysql using "net start mysql"!
And it started correctly :lol: I guess something was wrong with the files i previously created. Now i can go on configuring. see you later
