booting from linux live disc also fails , it cant boot from anything even from the disc drive when i select the disc drive from the boot menu it restarts again and same problem continues.The major problem i m facing is that the system cant boot from anything and in raid config ( as we can see in 2nd video) the hdd's are not found and in bios it is being showed . Is there any wrong with the sata chip ?
