Did you find anything in your Error Log (usually under the error_log file)? 

[alamillo98]

No, there isn't any log

Try adding the following lines to your index.php file and see if the front page will throw any error messages:-

error_reporting(E_ALL);
ini_set('display_errors', 1);

It will be very difficult to troubleshoot the problem with any error logs but do make sure that:-

1. All files are uploaded with nothing missing. The best way to do this is to upload the compressed file and only extract it in the server instead of extracting it in your computer and FTP the files one by one. 
   
   
2. Your server satisfies all of Magento 2's requirements, as shown here:-

Yes, i satisfied all the requirements, i've install it, but now, the admin link dont work or works but deformed and without images, if i put ur code, it shows 500 error

I kept getting this kind of error on the setup page too. I think it may have something to do with php 7.0.2. Try installing Magento 2.0.1

I'd also check your file/directory permissions
