I´m going to install Ubuntu 12.04 on my laptop, and I don’t have internet at home.
I know that I can install it without internet, but , does it work?

-Are you in need of an internet connection when you install it at a computer through a CD?
On the other hand if you are going to install using the windows installer (Wubi) which installs ubuntu at your existing Windows partition, you must have an internet connection in order to download the .iso and proceed to the installation.
However you should notice that if you do not have a working connection you will not be able to download any updates(except if you have an old release which is no longer supported by Canonical) from the update manager. You can always type
