Accidently reset BIOS.. missing operating system help

[wookieecrisp]

Hi guys,

I've accidentally reset my bios and now whenever I boot it says "missing operating system"! I have an Alienware Aurora and I really don't want to reinstall the whole os... please help is there a way I can get it back??

Running Bios Setup Defaults should not have done that
Unless you have your Windows system drive not connected internally in the right spot?

*EDIT* I think you might be right, when in windows setup it says my HDD is only 900 GB, it is supposed to be 2TB RAID 0. But in BIOS it detects 2 HDDs, each of 1TB.

Raid0 ?

If you have Raid Setup, then you need to go through the Raid Setup settings screen
Also enable Raid in Bios, then Save and Exit
I really hope you haven't mucked up your Raid config

YES!!! I finally got windows to start by switching some HD mode to "RAID" Thank you SO MUCH!
