I have a failed Raid1 array and need to repair or migrate it so I can boot from it again

I have a server for old medical equipment (2013, Win7) that was using an Intel RST v3.6 Raid1 array for the boot/OS drive. The server stopped booting and that’s when I noticed the bad array (no warnings – I think some recent work in the room cause power outages as workers were turning on/off circuits)

This is the raid1 setup as read in the bios:

disk1: error occurred(0)
disk2: member missing

Both drives spin, so to mitigate chance of data loss, I am cloning both drives to image files using hddsuperclone as I type this. One drive passed a quick SMART test too, but I didn’t test the other. Also, I’m halfway done with cloning the first drive and there are zero bad sectors. The power outages may have screwed up the array perhaps, but not necessarily the drives themselves – or maybe just logical errors.

I need to get this OD bootable again. I think I can “get the data back” by coping it, but that won’t help me boot into this OS.

Now, here’s my question:

After I image these drives, what’s my next steps to either repair the Raid1 array or somehow get this data to be bootable again in that server?

Since it’s Raid1, should I burn the image file to a new drive and then try to pop it back into the original position in the server (without Disk2 for now) to see if it will be picked up “error free”? Or, would a modern install of Intel RST help me “fix” the array? What about just burning one of the images to a new HDD and then using a non-raid SATA port on same server? Since it’s Raid1, would that work? Or, maybe just copy all of the drive contents and then run some sort of program to get the drive bootable in a non-raid way? I appreciate any help!
