http://askubuntu.com – I have first installed 10.XX version but later uninstalled and deleted the ISO image. then i tried to install 12.04 version but after installation from WUBI on first boot-up installation , it hangs on "Almost Finished Copying Files" I have given 16GB space in my Windows C Drive. I have tried to do the same 3-4 times by uninstalling and installing again. (HowTos)
