With windows 10 and Intel sata controller is there a way to fix an OS raid0 that initially booted into AHCI? PLEASE help very little of the data was backed up. I know this is raid/bios 101. optional rant explanation.
Warning- RANT---------Was ignorant enough to use a 3ed party Driver updater. [Software called Driver talent, garbage.] Without a warning visible or prompt my Bios was updated while “repairing” drivers for a simple usb device! Being unaware of the new Bios, the system tried to initially booted into AHCI destroying my OS drives RAID0. This is Raid/bios 101 am aware. 2.2 bios was great. 2.3 is pointless bloated, only adding “Change Internet Flash server.” Does anyone actually flash bios from the internet? I’m furious Asrock even included this feature. -------
BUILD- Asrock z77 foc, i7-2700k, sli 980 ti all watercooled, etc. Ran fine for years with stable overclock of 4.5ghz.
@ Aimbooze:
Welcome at Win-RAID Forum!
No mainboard manufacturer would silently update the user’s mainboard BIOS.
Is this an Intel RAID0 created by an Intel RAID Utility or a "Software RAID" created by the OS?
If you should have gotten malware into your BIOS, I recommend to order a new BIOS chip for your mainboard.

OMG help! Wonderful, thank you!
Greetings and wonderful forum. Kuddo’s!
first, the software “driver talent” caused this. simply tried to “repair” driver for a usb device.
Driver Talent did in fact update the bios silently. UEFI always showed 2.2, no need for 2.3 update - bloated with "change Internet Flash server."
I build my own pc’s and overclock, hobby.
Yes this is a RAID0 Intel, the CTRL-I still shows both my OS raid0 and storage RAID5 intact and bootable. Still Named correctly.
Although in UEFI, boot it says 840 pro as one boot device and RAID5 (named) as a second.
EDIT 1:
not software created, marvell/windows no. Intel chipset yes.
EDIT 2:
I also have extra Asrock bios chips already tried that 
EDIT 3:
The featured CTRL-I with intel chip sees both my OS RAID0 and RAID5 (storage), correctly named and bootable. ALL GREEN.
Although in UEFI Bootable devices menu the OS RAID0 was replaced. Instead it incorrectly show’s only one single 840pro not (840pro raid0) and the correctly named RAID5 (storage).
EDIT by Fernando: To save space and for a better reading I have merged the latest posts and removed unneeded empty lines.
"This guide only works if the RAID that has failed is NOT your primary boot volume. Some steps in Windows will be required. If it is your boot volume, some alternative steps for the Windows portion will need to be found."
Thank you, but that isn’t the problem. Or perhaps i’m not understanding. There must be an easier way. None of my disks or RAID have failed. I will continue searching. That might fix it, although it’s from
My boot disk hasn’t failed. Just won’t show up in UEFI I know from experience if i try this on my boot volume (raid0) a re-image will be required

As long as the Intel SATA Controller has been set to "RAID" within the BIOS, it is impossible to boot into one of the RAID0 member disks in AHCI mode.
Which name have you given the RAID0 array, when you created the array? Please run CTRL+I and look for the name.
Another question: Why is the RAID5 array bootable? Is there another OS installed?
I thought, that the RAID0 array is your system drive containing the OS and the boot sector.
Off topic:
no, one OS only…RAID0 - named "840pro" see image
No, the Raid0 is my OS only, drivers, Chrome, and Fallout 4 
The Raid5 video storage ONLY .mkv…
[Marvell sata controller has Storage has a Raid0 also, with Steam and other larger Games software.]
thank you all so much!!!
That is absolutely normal and nothing to worry about.
The Intel RAID Utility shows the RAID members, but the Boot Manager shows just the bootable RAID0 array as 1 device, It was you who gave the RAID0 airraiy the name "Intel 840 Pro".
What let you think, that your RAID0 array booted up as AHCI (see your thread title)?
By the way: If you or anyone else switches the SATA mode from RAID to AHCI, you will not be able to boot into one of the RAID0 array members.
China company Driver Talent.
Driver Talent, did a silent bios update.
RAID0 day 1 stuff- win10 still no fix?
i would NEVER let RAID0 boot into AHCI, {i learned by that years ago 
with my 1st pc raid0 build. but that was win7} Lesson learned, the reason i know it was a silent bios update. I had 2.2bios! Driver Talent Software made it 2.3 {silent} bios update. 2.3bios only adds "online bios update" feature. i only instant flash.
that is my question… is no way to fix a raid0 array after One boot into AHCI?
Still no fix with win10?
except delete array and rebuild and reimage?
No- see 1st image. - i named it "840 Pro". -Intel {ctrl-i} still have names correct "840pro"
See 2ed image. -New bios 2.3, booted into ahci , now UEFI named it "Intel 840 Pro"
----------------
Driver Talent did a silent bios update!!!
so
Default uefi booted as AHCI… then … i see … "missing OS".
I instantly returned UEFI storage config to raid (duh) not AHCI.
so
I know it booted only once AHCI screen was showing "missing os", UEFI storage config was in not set to RAID.
THANK YOU !!! 
Thank you again!!
before typing i knew… but do want to confirm… hope i am wrong
so reset raid array and reimage?
Although I don’t think, that it is required, you can
1. unplug the RAID5 member HDDs/SSDs.
2. enter the Intel RAID Utility by hitting CTRL+I,
3. delete the current RAID0 array and
4. recreate the RAID0 array by choosing both Samsung 840 Pro SSDs as members (Tip: Give the RAID0 array a name like "RAID0". This will help you to verify, whether any program is showning the RAID array or the single member SSD.),
5. boot off the USB Flash drive containing the Win10 image and Install the OS onto the freshly created RAID0 array,
6. Once the OS is up and running, re-attach the RAID5 members.
Fixed :(((((((((
But no fix ~~~~~~~
As standard with Win 7or8.
Didn’t unplug any SATA ports.
================================================================================================
Deleted the raid0 (ssd 840pro 2x)ONLY in Ctrl-I.
Rebuilt Raid0 in Ctrl-I (same drives).
Booted to Windows8 cd, (no windows 10 key, but free upgrade) now installing updates etc.
Installed Intel RST and the Raid5 was fine.
Raid 5 is now “rebuilding”.
Only needed rebuilt because of the 20-30x shut down incorrectly. probably a little data corruption but no hdd errors.
I tried everything else, win10 recovery. HDD regeneration software.
I found a Linix based guide with “recovery” - no fix.
Need a \command codes guide.

Thank you again Fernando. Glad u tried helping. Hope this “fix” helps you.
@ Aimbooze:
Thanks for your report.It is fine, that you succeeded finally.
Question: Why did you reinstall Win8.1 instead of doing a fresh install of Win10?
8.0 actually. not 8.1…
i had the original Windows 8 disk with key. Only the windows 10 iso. Windows 10 would not “validate” with Windows 8 Key.
Installed windows 8.0 Validated it with key and instantly updated free to windows 10 … lol, windows is still such trash, the 3 backup full backup’s i have of windows 10, i have remaining won’t re-image windows.
Have always used acronis true image… but window’s 10 was supposed to “fix” this longtime garbage feature.

Additionally now i’m having a disaster.
1} ASROCK- UEFI “H/w Monitor” Feature shows everything installed even USB, sound ports, every and all connected hardware or connected device! Great Feature!
Error is only one GPU nothing shown in 2ed pcie slot and same in Windows and nvidia only show one GPU found!. As if the other 2 slots are broken. This cannot be, it MUST be a bios or driver issue. Still working out a solution. Maybe set on 16x0x0 i’m not sure. Don’t have time to spend now on this “toy”.
No way BOTH slots are broken because the bottom was worked a month ago i installed a 3ed GPU card into it to test as Dedicated Phyx! Worked fine then.
Also have tested other working GPU in these slots, nothing only one GPU will work in top slot.
Sound card and Wireless card DO WORK in these slots
i’m very careful not to let the weight of GPU bend slot.
====================================================================================================================================================
2} ASROCK- UEFI Main system screen and UEFI overclock options shows 2 sticks of ram ONLY (16gb not 32g)
Although UEFI “H/w Monitor” Feature DOES recognizes 4 sticks of RAM installed (32g)!!! lol wtf
Also Windows Shows all 4 sticks 32gigs lol
I love building my own pc’s, but the struggle is real!
