I had to do a bios update after getting a new graphics card. Since the update, I've been unable to boot from the SSD that has my operating system (win 8.1) on it. The bios detects the drive and I can adjust boot order just fine. The problem persists in all SATA modes (IDE, AHCI, Raid). Clearing CMOS did not help.
When the SSD is the only drive in the boot order, I just get a prompt telling me to insert a boot device. When other drives are behind it, booting just falls through to them.
The mainboard is an MSI Z68A-GD65 (G3), the SSD is an OCZ Vertex3.
My next step will be to test the SSD on another computer, but meanwhile I wanted to see if anybody has any experience with this problem. It would be a huge coincidence for the drive to fail right as I updated the bios. Plus, I remember having the same problem with the old bios version, but changing SATA mode to AHCI always fixed it.
