Note that for most distros (excluding Slax, puppy linux and maybe a few others) UNetbootin does not actually install the OS to the flash drive or partition you put it on. Instead, is putting the contents of the install CD and installing the necessary boot loaders to make it bootable. It then runs as if it were a Live CD, which does not hold on to any of your changes.

If you want to actually install Linux with this, you have to run UNetbootin, then boot off the flash drive you put it on, and run the installer from your flash drive (more details here: Installing Linux With UNetbootin).

It’s also a good program for getting a portable Linux OS on your flash drive if you choose Slax, Puppy Linux and maybe some others.

That said, I personally have never used it so if this information is incorrect (and it might be) then please correct me. I just don’t want people installing Ubuntu via Wubi, seeing the terrible mess, and thinking that is how Ubuntu is.

@David: If you are into games then you might want to consider staying on Windows. Most games run on Linux in Wine, but some not so well. If you don’t need games, and don’t have a specific app that ties you to Windows, then I would definitely suggest trying Ubuntu or another linux distro.

If you do have one particular Windows app that you need, write to me (from the Leave A Message form at my site, link below) and I will check if it runs in Wine or if there is a Linux version / Linux alternative available. Here’s my contact link:

I stick with Windows because I need it for my work obviously and because it is comfortable. I know it, i use it, I do not have the time right now to make a switch. It’s in my mind for a few years but I’m probably a bit to lazy to switch yet.
