Repairing windows on broken raid-1

[Thedog]

Hello,

I did a misstake, I basically updated BIOS on a computer with raid-1 setup and then I got bluescreens etc. So I started to do some recovery (tried system restore etc) but everything failed. What I then realized was that the raid-1 had been broken by the bios update....

I can now boot into recovery environment with raid-1 but it wants to repair disk errors which I suppose will not work with raid-1?

Just as a quick thought, after a BIOS flash you will reset all the settings, just make sure your controller is set to RAID and not AHCI.

Yeah, the problem was that I tried to boot and repair with AHCI on (not knowing). So the data of the disk I tried to boot from is probably a lot different then the other disk...

I have now repair and currently on welcome screen (going really slow) so it seems I am making progress. Seems that Windows repair fixed my issue

Raid1 is just mirroring. Detach one of the drives before it gets fowled up so you have a backup. When you get windows running, take a backup and bring the other drive back online so the raid1 set can sync.

So, I guess I'd be safe in assuming that you didn't clone drives before you started messing around with it. I recommend that you stop and do that now, then set the originals aside and work with the clones.

Depending on the original RAID setup and the changes caused by you, this could either be a really simple fix or a really big mess. Let's hope that it is simple.

Good luck.
