I recently installed Ubuntu 12.10 on my PC since 12.04 felt super unstable this is a slight improvement.. any way when I start up my PC there are 2 Ubuntus in boot up that run the same OS nothing in difference, along with Windows Vista so there is something like this:
*Windows Vista
*Ubuntu -
(Problem)
*Ubuntu -
How can I just have one Ubuntu and please don't tell me i need to have everything obliterated! I don't want to remove Ubuntu all over again its super annoying and a pain.
