I put together a new rig with a new Asus Z97-A motherboard, 3.5GHZ Intel i5-4690 processor, 8 GB GSkill RAM, GE Force GT 650 and a Samsung 500GB EVO SSD plust two Western Digital 1TB mechanical hard drives. Both my Windows 7 and 8 DVDs are legitimate updates. Windows 8 came from Microsoft. I first tried to install Windows 7 and that would seemingly install but would never run past the opening screen when the balls spin and join. I then cleaned the SSD with diskpart to stop it from trying to boot to 7 and put the Windows 8 DVD in the drive. Following all the normal steps of a custom install it appeared that installation was going just fine. It installed all files without incident, rebooted and got to the "getting ready" screen and shut down quickly. The option I now have is to restart the computer and reinstall. That action results in the same result. In the UEFI BIOS I have CSM enabled and Boot Device Control is set to "UEFI and Legacy OPROM." I don't know if I have a failure with a new piece of hardware, a driver problem or am I setting something up wrong in the UEFI BIOS? Help me please.
