Still need help partitioning during clean install of Windows 7 64-bit

I want to do a clean install with my Windows 7 Ultimate 64-bit disc. Here's what I wanting to do.
I want a partition that I can install the just operating system on. It is important to me that this be a "recovery" partition...something I can use for a complete reinstall should I ever lose my Windows disc. In other words, I just want the files from the CD in this partition. I'm not worried about settings or data, etc. I have backups covered. Should my system ever get really messed up, I want the ability to access that partition and do a completely new install, adjusting settings later on if I want to. So, I want this partition to be a way of restoring Windows 7 my operating system back to factory defaults.
Then, if I need that 100MB partition, how do I create it?
And then, the rest of my disc would be for programs, files, etc Would I have to create an actual partition for this or just leave everything leftover as unallocated.

I could really use some specific help. I've been reading a lot of posts and tutorials and I'm still not getting it.
Thanks in advance!

It's not practical since Win7 has built-in drive imaging which can reimage your ideal Win7 installation to the HD or its replacement in 20 minutes. This is the modern way this is done and how those seeking to create an onboard Recovery partition eventually realize it is done best. Reinstalls are a thing of the past.
