Trying to install Vista on Dell, please help

My dell laptop has no OS on it right now (when trying to reformat it, vista got corrupted and is no longer there). So, I am trying to use a vista disk to reinstall it on the laptop but it stalls because it needs to have the sata drivers installed on the computer.

But, how can i install these drivers if i have no OS on the computer? Is there a way to do this? The laptop is a Dell Inspiron 1720.

Thank you for any help,
