I just built my first pc and it all went very smooth.
When I tried installing Windows 7, it would begin the installation process... I clicked "Install Now", then when given the options between "Upgrade" or 'Custom (Advanced)', I selected the Custom Advanced.
But it then said it cannot find any device drivers.
But the bios does recognize my hdd: Western digital caviar blue 500GB.
I have a gigabyte z77-d3h motherboard.
Is there anything i've done wrong? What should i be doing?
If the installer isn't seeing the hard drive it may not be recognising the the sata controller. There should be option to install drivers via usb or swapping the disc. It is probably easier to pop into the BIOS before starting and switching the sata controller into IDE mode then installing. You can install drivers after and switch to proper sata mode.
