    Going to install Ubuntu 12.04


    I am about to try Ubuntu 12.04. I've never tried to install or do anything like this before, any tips or advice anyone would like to tell me?
    I am downloading Ubuntu right now, I'm going to use my USB to install it on my laptop.

    If you've never done anything like this before, I would highly recommend trying it out in a non-destructive way before doing any kind of permanent or semi-permanent installation.

    In this order, I'd recommend:

    1. Booting the live USB and not installing it. Just use it live. It does not affect your Windows or Mac installation at all. It will run off the USB stick itself and your computer's RAM. It will not touch the hard drive. Play around with that for a few days before doing anything else.

    2. If you like the live session, go ahead and install it as a virtual machine in VirtualBox.

    3. If you like the virtual machine installation enough to set up a dual-boot, go for a dual-boot. On Mac, you don't have much of a choice--the dual-boot is necessarily destructive (i.e., you have to alter partitions on your hard drive). On Windows, you can use Wubi to install Ubuntu on a virtual partition on Windows without repartitioning the hard drive. This will still give you near-native performance (you will not be running a virtualized OS, but you will be running it on a virtualized partition).

    4. If you like it enough then to install it permanently... well, at that point, you'll probably know enough to ask at that point how to make it permanent.

    Okay, yeah. I meant I was going to try it live off my USB first. I just tried to run it off my USB and it worked but i cant connect to my wifi. Whenever i try to connect it says something about not using Certificate Authority (CA)

    It can detect your wifi but can't connect?

    Or it can't detect it at all?

    Can you paste this command into the terminal and post the output back here?
    Code:
    lspci -v

    It detects the wireless networks, but when i type my username and password and save. It just says that it recomends having the certificate authority. After i try to connect it continues to try to connect than it fails. Im trying to connect to my University network, maybe theres a certain way to connect to the network?

    You should contact your school tech support about that.

    See, for example, how Cedarville does it:

    I got everything working, I'm using Ubuntu right now but I'm running it live off my USB still to test it out. I downloaded Chrome and Python to play with, but when I turned off my computer and turned it back on they weren't there and nothing was saved. So, how can I save my programs I download onto the USB so i can resume playing with Ubuntu? I don't want to install Ubuntu just yet.

    The point of the live USB is that it isn't permanent. As I mentioned before, it's running off the USB image itself and your computer's RAM.

    There are ways to "install" it without doing anything destructive. I'd highly recommend using VirtualBox to do so. It's available for Mac, Windows, and Linux for free.
