My blank CD's are only 700 MB, and the
.iso file I downloaded is over this. What do I do?
You can use the Business Edition .iso file you downloaded with Startup Disk Creator, and make a bootable usb thumb drive version of the business edition, or burn the ISO to a DVD instead. You will more than likely need to go into your BIOS and change your boot order, or use the boot menu option (to pick a temporary boot device) if your BIOS supports it. Hope this helps!
