Cleared BIOS, lost RAID array, need to fix it so I can load Windows

post #1 of 5
Thread Starter 
Yesterday I unplugged my desktop to hook up another temporarily. After dealing with that and reconnecting my sig rig, I've discovered the BIOS has been cleared. How? Not sure, I probably accidentally hit the clear CMOS button which is stupidly on the back I/O panel (I hate you ASUS). Maybe there is a deeper issue, but hopefully not.

This is a problem because I had two hard drives in a RAID 0 array, so with the BIOS cleared and the RAID array broken, it cannot detect an operating system. I REALLY need to get the RAID array back up in a way that will allow me to load my previously installed Windows. If I have to reinstall Windows I am going to be miserable... lost files, alllll those programs and settings to re-establish.

So any advice? Right now I have three hard drives connected, the two that WERE in a RAID array and an extra 1 TB storage drive. I assume I remove the storage drive so only the two drives I want in RAID remain, and I switch it from IDE to RAID in the BIOS? I cannot remember how to do all of this, I've been removed from the wonderful world of computers and overclocking for a few years now. And the stakes are too high to rely on slightly relevant articles and forums from goolge searching. I'm hoping for some good old fashioned help from the site I use to live on haha.

Was it just like I said? Switch it in the bios from ahci to raid on both drives?

Intel onboard RAID is pretty smart, you could actually take those disks to any other modern intel board, enable raid, and while it might not boot if the hardware is too different you could see the array and browse it from another install.

So yes, as you have already figured out this is as easy as giong into your bios and enabling RAID again. Then your array will show up. You may have to go and set it to boot from the array if you have other discs in your system.

You don't have to unplug any other disks, just make sure that the RAID array is first in the boot order.
