I installed Ubuntu 10.04 on a computer with Windows on it (and later upgraded to 11.04 and 11.10). Now I can't remember whether Ubuntu was installed inside Windows (Wubi) or in its own partition. How can I find out which is the case?
Open your file browser and click "File System". Do you see a
Open "Add/Remove Programs" from the control panel. Is 'Ubuntu' listed among installed programs? If so, Ubuntu is installed within Windows.
ok, you should open your control panel inside windows and see if a software entry by the name of ubuntu is present or not. If not the ubuntu is installed outside windows and vice versa.
