This question already has an answer here:
I am totally new to Ubuntu,I have download the latest Ubuntu 12 64bit(ubuntu-12.04.4-desktop-amd64.iso) from the Ubuntu site,the file is approx 700mb.
I want to install it on my laptop(currently on windows 7 32bit) that's why i copied the file to my usb then paste it to the c: drive of my Windows platform,(the file is in rar format) that's why i extracted it and found that there is wubi.exe (which is the Ubuntu installer for windows).
Now what should I do, do I? Just click the wubi.exe and follow the process, will wubi.exe need any internet connection to download any other extra file or 700mb is enough.
