Need help for RAID Volume issue

I got this used PC Dell Optiplex 780 with a HD in it and last year I ran out of room so added a 2nd HD and all worked great until recent when I changed the battery on the motherboard.

I easily changed the battery and then when booted got this Bios page 1 regarding RAID Volume and when keyed in CTRL i when to a 2nd page (I have subbed pics of Page 1 and Page 2a and 2b - reason for 2 pics of 2a and 2b is because the highlighted area cursor is on you cannot read what it says).

I have never used RAID Volume and do not know what this means. I read a little about it and sounds like some back up is created in the HD but I do not need this as I every week back up my PC stuff to external drives x2.

I need your help to select correct answer (I think it is 2. Delete RAID Volume but makes no sense as pics show Non-RAID Disk). I read that if select Reset Disks to Non-RAID it will delete the HD's - pls let's not do that! So you see this is all very confusing and I can sure use your help. I think the correct answer is Delete RAID Volume but am not sure about this.

If it had only one drive, it wasn't in a RAID array to begin with.

You do not want to delete RAID volume or Reset Disks to Non Raid. Both will delete the data.

If you have a backup as you mentioned, the worst that could happen is going through the steps to recover from that backup.

Can you get into the BIOS? In the BIOS there may be a setting to change the setup from RAID to IDE or ACHI. IDE may be the only other choice dependent on the age of the computer and version of the BIOS.

Curious what's under choice #4?

Extra info to assist troubleshoot:

That Bios page I am getting stays there a few seconds then system goes to windows, it is just an annoying page that seems to be asking me to config RAID (I never had this before I changed the battery, bizarre)

-OS is Win 10 64 pro

-In the F12 Setup for OptiPlex we have:
Okay so in the OptiPlex Setup we go to Drives/SATA Operation and there are 4 choices:

1 RAID Autodetect / ACHI

2 RAID Autodetect / ATA

3 RAID On

4 Legacy

It is selected as RAID On,
I have already tried to select RAID Autodetect / ACHI but PC will then malfunction and does not work.


-I will later try a test (unplug the HD 2 that has all the important data) and then reboot to see if that Bios page shows up, if it is gone then this Bios page is related to HD 2 and we can isolate the monkey there.

That BIOS page is the Intel I/O Controller.

Have you tried ATA? Legacy?
