Try any flavor of a Linux LiveCD like Mint, that you can boot from to read your files and copy to an exterior storage device. http://linuxmint.com

Another great tool is Hiren's BootCD that has plenty tools for saving your current installation of windows. http://www.hirensbootcd.org/download/ There are a couple of misleading download buttons on this page. You want the one that looks like image below.
You will need to burn the iso contained in the zip file with image burning software such as ImgBurn. Good luck
