remove your email so you dont get spammed. if you have the windows boot cd boot from it and go into advace mode and delete all the partion on your hard drive. then reboot and let windows 7 make new ones. just be care full as most laptop vendors put the restore partion for windows on the hard drive now. if you dont have a cd-rom drive from another pc you can download hirem boot cd and make it bootble usb stick or use the windows iso to usb tool to make a bootable usb stick.
