So - did you update bios or not. Can't understand that.
If you did, then bios settings have been reset and you have to restore sata controller mode setting to previous value.
Possible values are: IDE, AHCI, RAID. If you're not sure about the right one, then try all (most likely AHCI is the right one).
I downloaded an older version for some reason. Downloaded the newer one q flash installed it and everything seems to be working. Tried shutting off the computer twice didn't get BS. Also I didn't forgot to set the settings back what they were.
