i am trying to install windows 7 on a gigabyte GA-k8ns ultra-939 motherboard and when it asks for the location in which i will install the OS it wont show any hard drives at all. i have 2 500gb hard drive as where one has xp64 bit installed on it. is it that the SATA controller doesnt or isnt windows 7 64 bit compatible? ive tried on both 32 and 64 bit versions. is there a bios update for windows 7 for this chipset or am i wasting my time?
