after uninstalling Acronis, my hard is not de

I have Dell E6500 with vista. When I uninstalled Acronis, then I got loop of booting. I understood that I have to clean my regedit from snapman. However the when I use the Vista DVD, it does not detect my local hard drive at all to dill into my config. What can I do???? I even can not install a new vista, since my hard derive is not detected.
