I need to remove Ubuntu 12.10 so that I can install XP Pro. I tryed using Gparted but it gave me the error message, "The partition could not be unmounted from the following mount points. "/" Most likely other partitions are also mounted on these mount points. You are advised to unmount them manually. I have tryed using "Fdisk" at the command prompt, but the commands "p", and "d" would not work. I have no idea what to do here. Can anyone help. Or do I need to follow another path.
