I am trying to install ubuntu 12.04 inside windows 7 using wubi.exe (downloaded separately from Ubuntu forum to get the option to install inside windows).
when I restart my machine, ubuntu installer begins by verifying the installation. It fails in the middle giving "no root file system defined".
As far as my knowledge goes, when installing inside windows we are not required to choose a file system and all the process are completed by the installer on its own.
Please let me know if there is any additional step required in this process or if possible how can I remove this error?
