I have an ASROCK 890gx pro3 MB and GSkill Phoenix Pro 120 gb ssd. The BIOS screen shows the ssd. I have already installed a copy of Windows 7 to my samsung 2 tb HDD but also wanted it to be on the SSD as the primary boot option.I disconnected my HDD, changed the BIOS boot set up to AHCI and Windows installer would not show the ssd. Changed the boot set up to IDE and still no luck. Any suggestions? Thanks.
