This is my first build and I have just about had it. My OS windows 8.1 will not down load on my drive, I have 3 drives, when I install the OS it shows all three drives but says it cannot load the OS to that location. I am using an adaptor card for the SAS drives it is an x8 I put it in a PCIe x16 slot that the motherboard documentation says will support 3.0 x8 I'm not sure if that could be the problem. I formatted the disks when it ask the location to download the OS I click on new and it tells me it might have to make other partition I click ok and it comes back and say it cannot partition. I don't no what else to do, well I could take the whole thing and throw it in the lake I guess.
