I need to install the internet card drivers on my netbook the problem is that it doesn't have CD tray so I can't install them via the Cd or at least I don't know where to mount the ISO so Ubuntu recognizes it so I can put the Proprietary Drivers. So is there any other way? Or where can I mount the ISO?
Try this, taken from here How to use a .iso image as a CD-ROM Repository?
If you want to use the ISO image as a software source without burning it, the process will be a bit more complicated. You will need to open a terminal Applications -> Accessories -> Terminal and run these commands:
sudo mkdir /aptoncd-mountpoint
sudo mount /media/USB/aptoncd.iso ~/aptoncd-mountpoint -oloop
sudo apt-cdrom -d=/aptoncd-mountpoint add

You can install .deb packages by double-clicking them, so just install them that way from the mounted .iso image?
When it asks for your cd, you can mount the ubuntu iso from the website, in the way that the other 2 people have told you.
Once it is mounted, you can add the mounted iso in software sources as a software cd. Then you should be able to install from there.
Do you have the option to get internet using an ethernet cable? That would be the easiest option for you.
