Windows 7: PC will not boot after update

PC will not boot after update

Hi guys,

Sorry if this is in the wrong place

Last night my PC did a couple of security updates and did a nVIDA update - I can't remember if this was for the on-board sound or the motherboard (I assume the later).

Now when ever I try to turn on my PC I see the "BIOSTAR" Logo, for what feels like ages, and then I get a list which ends with "3rd Master Disk error - press DEL for BIOS set-up"

In the BIOS I noticed that I can't add my SATA drive into the boot priorities list.
When I look at my SATA drive it shows as having 0 MB - which is utter rubbish!

I've tried setting the SATA drive into ACHI mode - but this just leads to the PC trying to boot from the CD and saying "no media present".
Please Help!

Why does Windows have to be like this

Using your Windows 7 disc, enter Automatic Boot Recovery. It should detect and fix any issues preventing the system from booting.

This is a good suggestion!

however before doing this, I would make a backup of your disk, i.e. pull it hook it up to a drive adapter to another machine and offload your files. Too often I have seen people try to repair a booting issue and then their files get hosed in the process.

You may want to reset your bios to the defaults settings. Sounds like something messed up your SATA settings/drivers.

If that doesn't help, perhaps try changing the option for a PnP OS installed to No or Yes, depending on what you currently have.

Can you boot to the Install DVD?

Thanks for your help so far guys... I'm really at a loss now. Windows own update has turned my PC into an expensive table

Did you reset your BIOS like Saltgrass suggested?

Uninstall/roll back the updated driver .... if you were doing okay with the way it was, then that could be the problem.
