creating partitions and multibooting...

I want to multiboot with windows and 4 or 5 different distros. I have two hard drives, one for windows only and the other for linux distros. I just installed the drive for linux distros, so the drive is not formatted yet. What do i need to do to be able to be prompted for which OS to boot from? Also, i want to make four 20 GB partitions on my linux drive, what parameters would i need to set for each linux distro?

Thanks in advance!

Boot up from GParted or PartedMagic LiveCD and create partitions in Linux HD. GParted is available in a few LiveCDs like Fedora and Ubuntu.

Plug-in Linux HD as Primary Master and Windows HD as Secondary. Linux installer will setup dual boot itself. Keep on installing new distros and installer of every distro, except Fedora, will detect all other installed distro and setup multiboot for you.
