just wondering how do i freshly install vista without the cd, i currently have vista and ubuntu installed i press F10 then it takes me to the screen where i have an option to choose which operation system i want not the reformat option.
You really should have created an image file the last time you installed Vista, saves heaps of time and is easy to do. I suggest getting a copy of Tru Image 10.
you could just download a copy of vista (would need to be put on a dvd) and use your legal product key (assuming the vista you have atm is legal). otherwise you cant really do much, unless your pc has a recovery partition.
