I have UBUNTU 7.04 want to get new do i need to install new drivers for new fiesty

hi:

you mean you want to upgrade to ubuntu 7.10?
just follow this guide:
http://www.ubuntu.com/getubuntu/upgrading
the system will take care of all you need, and of course if you need anything else, all you have to do is make a question

thank you very much can u please tell me how do u rate 7.10 in front of 7.04 .
I am a beginner in Linux and started using it 2 weeks back finding problem in operating through the terminal.
From where i could get the commands.

U mean i need not to Uninstall the last version

you don't need to uninstall the last version to install the latest version, you simply 'upgrade' to it

Thanks
