copy .htaccess file from your magento installation package and if you didn’t find .htaccess file then your magento installation package is incomplete.
You can use the attached .htaccess file and put it for Magento root directory. Tell me if it works
Just a tip: if you are using FTP to transfer the files, some FTP applications by default does not show “hidden” files that start with a . (dot), and thus it may not be included when you transfer the Magento files. You should find an option to show hidden files in the application settings.
