Question I was unable to install Windows 2012 R2 on X10DRI motherboard with enable RAID on SATA Configuration and sSATA Configuration. Is it a bug? Answer No. It is not a bug. It is limitation of the BIOS firmware. Work around solution: 1. If user plan to install OS on hard drives install on SATA Configuration, in BIOS->Advanced->SATA Configuration, select "SATA/sSATA RAID Boot Select" as "SATA" instead of Both after create raid configuration on sSATA Configuration. 2. If user plan to install OS on hard drives install on SATA Configuration, remove the hard drives install on sSATA Configuration ports. After finished installing OS, shutdown the system and connect hard drives back to sSATA Configuration port. Was this FAQ helpful?
