I had downloaded Ubuntu 12.10 today morning, in torrent form, it was about 700 MB. Than I clicked the setup which is `Wubi.exe´. It completed the downloaded, than It stated "EXPANDING" , It expanded more than 50%, and now it (the progress) has stopped? It's been like 3 hours, and not a single percent has increased? What to do? As I am writing now, it's still showing expanding, Please Help, and by the way, I am new to Ubuntu
For a Wubi-installation (installing Ubuntu IN Windows) you don't have to download 700Mb; simply download direct the Wubi-installer from the Ubuntu website.
In Windows execute the installer and you Ubuntu-version will be downloaded and installed in Windows. On boot you'll have a text-based option to choose Ubuntu for starting up (or Windows itself).
For setting up a dualboot (Ubuntu side by side with Windows on different partitions) you'll need to download your complete Ubuntu-ISO and burn it to a disk (or making a bootable USB-stick). Then you'll have to boot from this burned disk in order to preform an installation.
