I just built a new system with an MSI Z87-G43 MB, Intel Core i5 4670k CPU with integrated graphics, 1TB HDD and 2 OCZ Vertex 2 90 GB SSDs. I enabled SATA RAID in the bios (v. 1.1) and in the Intel RAID setup I set the 2 OCZ SSDs to be a 172GB RAID array which it said was bootable. I went to install Win7 X64 on the RAID array and the Windows installation said that it could not install to the RAID array because it was not bootable. I don't get it. Intel RAID set-up says that the array is bootable but Win 7 X64 install says that it is not bootable. Can anybody tell me how to make this installation work?
