My existing motherboard died - Asrock Z87 Extreme6. I can't find anyone selling it anymore! Does anyone know of a source? OR, does anyone know if I can use my Windows 10 or Windows 7 installation on my hard drives to boot an Asrock Z87 Extreme4. Long story on the Windows 10 - got a "free" installation on the "Windows Insider Program" - have ISO but don't want to go through registration process & transfer hassle. Windows 10 doesn't have a migration tool now. There are other alternatives but I'd rather take the easy way out... HELP!
