Base on my research it says that I should have set my SATA to AHCI mode but my BIOS don't have those settings. And I found out that there is another way to fix this. I have to install ktext in order to bypass AHCI but still my Disk is not showing. It only shows my USD Flashdrive. Is there any other option to make my disk show up on the disk utility? Or there is a specific version of AHCI ktext for the specific Motherboard?
