Red Hat 7.4 over R740 equip. with PERC H740P doesn't boot

Hi,

I have a R740 equipped with a PERC H740P Raid 0 and 4 SSD 1.5Tb each. Installing via USB a Red Hat 7.4 all is going fine except after rebboting. Machine doesn't find any boot device either using BIOS or UEFI.

Thanks to help me.

Regards
