Finally installed a new version. Completed the setup, loaded it into BIOS, but now I'm stuck. I retained my previous M.2 and HDD from an earlier build and transferred it here. However, it seems only half of it is being recognized. In EZ Mode it displays both in RAID details, further under Storage Information, yet when I open the Boot Menu, nothing appears. Could you assist?
In your UEFI/BIOS configuration, verify the SATA controller is configured as AHCI, not RAID, unless your previous setup didn’t use RAID. If RAID was used, you’ll need to restart Windows because it likely relied on a hardware RAID solution that doesn’t integrate smoothly with new controllers.
Background note: Most systems today use two main RAID types—hardware RAID and software RAID. In software RAID, the system defines the RAID setup through software, letting it manage drives without needing special hardware. Hardware RAID, on the other hand, relies on the controller itself to handle RAID operations.
Software RAID tools like Windows Storage Spaces or TrueNAS work with any RAID configuration, while hardware RAID controllers are tailored to their specific hardware. You can’t just swap drives between different RAID controllers unless the manufacturer allows it. For instance, transferring from an HPE SmartArray controller to a LSI MegaRAID won’t retain data unless conditions match.
It’s wise to back up your data before changing controllers, especially if you’re unsure about compatibility. If your old system used RAID, it probably depended on a hardware RAID setup that can’t be directly ported to another controller without risking data loss.
I'm going to make some educated guesses: You weren't using a RAID array on the old install Your old drives are old enough that when you installed Windows on them, you used an MBR partition That is not compatible with UEFI boot To fix it, you'll need to enable CSM in the UEFI like @Sjaakie stated Now, here's the part where you'll need to provide us more data, even if you weren't using RAID the old computer may have been set to RAID in the BIOS which means your Windows is using RAID drivers What motherboard/computer are the drives coming from? AMD or Intel? What is your new computer motherboard (AMD or Intel)? If they are both Intel, there's a good chance you'll be able to boot after enabling CSM Try leaving the UEFI storage controller setting on RAID and see if it boots If it doesn't, try AHCI Post back here and let us know how it went/where you're at
Please share the motherboard details for both your current and previous systems, including the manufacturer and model numbers.
Check if Intel Rapid Storage Technology (RST) is active or inactive. It functions as the RAID controller on your latest motherboard. Note: On older models, the SATA storage controller is an ASMedia unit that doesn’t support RAID. Ensure RST remains disabled on your new board to route drives directly to the OS.
