Ok, so after making a ubuntu cd and trying ubuntu out on it, I decided it would be a good idea to try and dual boot my old laptop with windows xp home edition and ubuntu 9.04. First i tried to partition the hard drive, but that did not work, so i researched it and decided to use wubi instead. I went through that process and put aside 6 gigabytes for ubuntu to run off of. The process went well, and for a while both systems worked together. After awhile, though, windows would not run untill I did like a "clean disk process?" or something. I believe it erased something important to the ubuntu booting system, because now ubuntu will not run, it only goes to a shell, and when i select windows to run, it only restarts the computer and displays the "chose which operating system to run" window again, making it run in a continuous circle. I am only able to post this because i am using the ubuntu cd that i made earlier. It is my goal to have ubuntu off the computer and to have windows back running again. could someone please help? i promise to never mess with this sort of thing again... any advice would be much appreciated. Also is there any way to do this without the windows cd? i lost mine.. thanks
