Can't install Router OS 6.40 on one of my Dell Servers R710

Hi guys,
I’ve been trying to install Router OS 6.40 on one of my Dell Servers R710, unfortunately the installer doesn’t recognize the hard drive. I tried with (disks on RAID and without RAID config) the H700 RAID card and nothing, also tried with the PERC 6/i RAID card and nothing, Any idea?
