hello every one
I changed the bios to this setting :
mass storage controller configuration :
intel SAS RAID module : disabled
onboard SATA controller : enabled
SATA Mode : SW RAID
I have 2 hard that is toshiba 1T.
when I want to install windows server 2012 r2 and 2008r2,I face with this problem:
I also downlad raid driver,it detects the driver but after selecting the driver,face with this error again.
I disabled both SAS and SATA raid controller,but face with this problem again.seems not detect non of hard drives,but I can see hard in boot menu option.
