I bought new computer parts and built it myself. When I try to install windows it won't find hard drive or when it does then it won't allow to install on that drive (gives some error, windows cannot be installed to this disk). I checked bios many times and sometimes it can recognize hdd and when I restart then there isnt anymore. Boot menu doesn't show hdd at all. I tried another hdd, flashing bios and connect to other sata port, but still nothing.
