I am going to have to step in here. If you use the CD version of the install, you have full control over what partitions to install on or create, and how big to size everything. It is a slower install than the DVD version, but, the DVD version is made for ease and simplicity. Please read the content available to you, before making hasty decisions, you may be able to do a lot more than you think.
I have a system at home running, gentoo, mandriva, suse, and LMCE. This system was installed using the CDROM method.
Just food for thought

p.s Here is a good place to start, and it was right on top in the Forums, under Installation, how ironic
