Hi,

This should be a pretty simple problem to solve.

I have the ASRock B550M-HDV with 4 connected SATA drives, in no particular order:
1. 250GB SSD (Windows is already installed here)
2. 500GB SSD (just data)
3. 2TB HDD (blank, no data)
4. 2TB HDD (blank, no data)

I want to make a RAID 1 array out of the two 2TB drives and boot from the 250GB SSD.

In AHCI mode (Advanced -> Storage), I can boot just fine from the 250GB drive, but I don't have the array.

In RAID mode, I can apparently make an array, but I can't select the 250GB drive to boot from it.

I've read the docs, but not clear how to achieve this specifically.

Any suggestions?
