I really hope I haven't screwed up. My old motherboard with an Intel X77 chipset died so I have a new motherboard with the Z490 chipset. I had a raid-5 with four hard drives on the old motherboard with a SSD as my boot drive. Setting up the new motherboard it told me to turn on raid, so I selected "SATA Mode Selection" = "Intel RST Premium With Intel Optane System Acceleration(RAID)". BUT, it looks as though it's trying to use ALL the drives in the RAID, with no drives identified as bootable. So I've set the SATA Mode back to AHCI and removed the four RAID drives, but it still doesn't see my SSD as bootable. Did I just loose everything because of that one setting? The fact that to have a RAID it's all or nothing seems ludicrous to me. If I haven't lost everything, is there a way to get my RAID data back?
Thanks for any advise.
It finally came up the way I needed, but I had to transfer my OS to an M.2 drive and then turn on raid with legacy support. Once I did that the raid came up just fine.
