I remembered the last time I use wubi, I can install Xubuntu from local ISO image.
and today, when trying to install Xubuntu, wubi trying to download Xubuntu ISO. there is no option to choose local ISO image.
I've tried to put Xubuntu ISO in the same folder as wubi installer, and close internet connection... both not works...
I use unstable wireless internet. It rather impossible to download until finish big size Xubuntu ISO from internet
