Here's whats happening, i replaced my old mobo a Gigabyte ga-970a-d3 with a sabertooth 990fx r2.0 now I've kept all the same hardware i have been using even the old boot HDD and i have the windows disc from my old mobo install but no key unfortunately. Will i need to reformat my hard drive to get this to work? Is there anyway to keep my data and just reinstall windows? Will i have to reconnect my old mobo and back up all my files on to an external drive? Any additional information needed i will do my best to provide. Thanks in advance for any possible help I'm really not wanting to call a tech guy for a possibly minor issue.
