Hi Robert Thanks for your message, I resolved the issue The boot sequence was set correctly and I also tried to boot from the RAID directly, the problem was the firmware. I updated all firmware and that fixed the problem.  Thanks for your help Farshad 
Hi So I configured Raid 1, installed Windows server 2012 R2 from USB. But when the system reboots after installation is complete it says there us no boot device available. I tried to manually boot from the raid controller but still says the same thing. The boot is BIOS. I'd appreciate it jf you could help me to vet this up and running. Thanks Feri
