DUAL BOOTING UBUNTU AND FEDORA

Hi,
I am a windows novice, its not that i am slow to learn or something but it is because i find windows too simple to use and belong to the douche. Since it autoruns everything that it detects and currently caused my computer to freeze severally, due to spam and viruses .This has made me totally divorce the windows thing and since i'm a linux professional i have decided to divorce windows operating system completely.
i want to dual boot ubuntu ultimate 10.4 and fedora and i am wondering whether they will both share the logical partitions required for their installations, especially the root, boot and home partitions. i know that i sound so geekish , but for those who get what i mean i really need your help since the whole windows thing sucks and got me wishing another version was never released. For those who don't understand, what the hell i am talking about welcome to the open source world where everything is free and can be manipulated anyway you want.You can even make it for your own trademark and virus as in you don't need to install any anti virus or any of those crap meant to protect your computer from the "virus" thing.
Thanks.
