Hello everyone! I recently purchased a new g75vw, which came preloaded with windows 8. I proceeded to downgrade to windows 7 (on an added 128gb samsung 830 ssd), which proved to be quite the task in itself. During this task, I updated the BIOS from 217 -> 223... Windows eventually got installed through a USB, and could not boot under SATA setting of AHCI. Running the computer in IDE worked, but I wanted the benefit of AHCI.. so today I figured I'd research and try to figure out. I eventually got to the point of resetting to "factory defaults".. low and behold, now the computer instantly boots to bios. It -will not- boot anything else, it doesn't show either hard drive or cd drive in the boot options (though they show in the sata configuration page). I can get a USB stick to show in the boot menu and options but it own't boot those, it just goes right back to the BIOS.. Help? Dustin
