persistence

I am currently running Ubuntu as a guest vm on a Win 7 host via VirtualBox, but I would like to have a portable version of Ubuntu when I am not using my laptop.

I am unsure as to the difference between the following:

1)LiveCD with persistence; 2)LiveCD without persistence; 3)LiveUSB with persistence; 4)LiveUSB without persistence; 5)Full-install.

I have a USB flash drive (32GB), and I also have empty DVDs lying around. I know that persistence means that data can be saved, but I am unsure as to which option to choose. What is the difference between a LiveUSB and a full-install on a USB thumbdrive and why would I want to pick one over the other? Thanks for any help.

How do I know if I am running Wubi or a proper dual-boot?

as seen on Ask Ubuntu - Search for 'Ask Ubuntu'
I tried to setup a "proper" Windows/Ubuntu dual-boot system, by installing Ubuntu from a USB key. However, I simply could not get the laptop to boot off the USB despite the fact that I made the appropriate changes to the boot device order in the BIOS. So I then turned to Wubi, and (to cut a long… >>> More
