My computers run Windows 7 and one Vista, all are 64 bit. Can I install Linux 9.10 or what. Can I run both 7 and Linux?

I predominantly use Windows 7, but I like messing around in Ubuntu IF I can access my files in 7. Could someome please give a very clear (in "stupid" terms) description of how to mount my harddrive so I can access all files in both OSs? Please and thank you.
