I used to try to run an operating system with this program but if I remember correctly it told me that my processor does not support it or something. Can I change the settings from somewhere or something similar? (I have Windows 8)
if your system is Windows 8, your processor will do just fine. Only pay attention to the version you will download, if you are running Windows 64 bit download to install the 64 bit ISO
