Recuperar Datos Disco Duro Externo Mac

I did some research, and found out that I should use EasyBCD, but I'm not sure if I can burn it on to a CD and then boot from it? (I have only 700 MB CDs available)Or if there's another tool that I could burn on to a CD that would let me remove the Windows 8 boot loader, and just let me boot to Windows 7.
