I would suggest that you do not multi-boot the system because backing-out of the changes will basically result in you having to reload the OSs from scratch. My suggestion is to install a VM product (VirtualBox, VMWare, or Virtual PC) on your Windows 7 host computer and create guest VMs that you can easily load and delete when you are done without modifying your host operating system at all.
i like to have multple OS's because of compatiblity & stability. if one goes down boot the other. plus then i can advise ppl better if i have the OS they are using at my fingertips. you have to be very careful that you do not waste your Windows 7 key, if it is a retail key, do not worry about it, if it is a MAK(multiple activation),be careful, you don't want to waste the activations. if you want to transfer your retail key to another machine, you must first deactivate it on the old machine.
as mentioned, start by creating partitions
another method is having multiple hard drives and then using the BIOS to boot from different hard drives.
