Reinstalling Mac + bootcamp

[saladfingers]

Hello, I have a macbook pro running snow leopard with windows 7 on bootcamp. I've had this computer for three years and it's starting to get a bit slow and buggy, I'm going to university in a week and a half and before I go I want to perform a clean install of snow leopard, upgrade it to mountain lion and to reinstall windows.

By reinstalling i mean starting over again fresh by formatting the hard drive etc.

Can anyone tell me the easiest way to do all this? I have the snow leopard and windows 7 discs.
Thanks.

Backup your files.
Boot up from your SL disc (hold "C" at startup).
Use Disk Utility to wipe your hard drive and repartition it into one partition.
Install SL.
Run Boot Camp assistant and setup Boot Camp.

Done.

GimmeSlack12 gives you a very simple and good way. Either you can clone your hard drive using any tool and keep that clone as a backup for your drive. There is another way if you want to keep both SL and ML, install ML on another Volume. If you want a clean install then use SL installation disk and erase your hard drive with disk utility then install SL and upgrade to OS X Mountain Lion. Check compatibility before upgradation.
