I just built my first computer and am trying to install windows 8.1 64bit to my ssd but I get a message saying that it can't write to that disk and that i need to enable disk controller. I've googled this problem and even read forum posts on toms hardware about it. I have made sure its ahci and the SATA ports are enabled and even though people debated if the boot drive needs to be in the first SATA port I out it there anyway. The only thing I haven't done that they suggested was update the firmware and bios. Which idk how to do without having a running operating system. However I did notice when I was checking ti make sure the SATA port was enabled that in BIOS it doesnt recognize my ssd. It only shows my optical drive. But when I have the windows disk in it shows my optical drive. I have gaZ97hd3 mobo and patriot pyro 120gb ssd. Sorry for typos on mobile. Please help!
