I downloaded ubuntu as an ISO file. I've transferred it to a USB Terra Bite. Its now in the form of multiple files and folders of which my computer cant read or open. There are two exe files. One named "wubi.exe" and "USB-Creator.exe". when i click on the wubi file it brings up a pop up called "ubuntu menu". I now have the option to click "demo and full installation" or "learn more" when i click demo and full installation it gives me the choice of "reboot now", "i want to manually reboot later" or "help me to boot from CD". if i click the CD one it begins to load but takes over 28 hours apparently. Can anyone help me to complete a full installation? I dont want to replace windows either. Will i loose my personal data and files if i reboot.
