Ok i have downloaded an iso for a linux ubuntu based os called eeasy peasy. How do i dual boot Easy peasy and windows 7?

You need to make a partition on your hdd. You can do this by right click on 'Comupter' or 'My Computer' then clicking 'manage'. After that go to 'Disk Management' and partition your drive. Then load up a ubuntu live disk and install it to the newly made partition. Then you've dual booted them

Make sure your hdd is large enough!
