I have already tried many times any time during the boot but nothing.
Thank you for reply
Are you still having issues with this? I had a weird issue with my RAID array built on an Intel controller. My BIOS settings were somehow lost after a crash, and it would not not recognize my two drives as RAID members, or let me into the Intel controller config BIOS. I looked over the BIOS settings, and saw that it reset the SATA options to "IDE" instead of RAID. My motherboard is an ASUS and since the layout is a bit different than Gigabyte's I'm not sure where exactly you need to look.
Once I got the BIOS reconfigured, it let me use the Intel BIOS again, and thankfully it recognized my striped drives without me having to rebuild the array.
