Well, I'm sorry for not better clarifying my problem. I'm currently sick of Windows OS, and I've really wanted to try Ubuntu, a type of Unix OS, for a while. It really appeals to me, and I would just reboot the computer and install it, but this is a family computer. I do not have any other computers, and buying one is out of the question right now. After doing more research to my own question, I've discovered a way to do it, at least somewhat. I was wondering if this would work...
-Create a new partition and giving it a decent amount of space using fdisk,exe on the Windows start-up floppy.
-Install Ubuntu into the partition.
Now, I've found a program called GRUB which has a nice tutorial for multibooting like this, you can see it
here. Once I have the OS installed and partitioned, then how do I separately boot up Ubuntu at start-up as opposed to Windows? Do I need to make any other partitions for Windows/Ubuntu?
EDIT: I've also just stumbled across some info in a LiveDisk. Does this disk just load up the OS when I put it in, and just run off that, like it's own contained OS? Does it keep hold of files, how exactly does it work?
