Thank you tomasz86 , I do appreciate your interest and help. I tried turning on RAID for just the SSD (I have never used RAID and am not familiar with it), BIOS allowed me to turn it on but then doesn't like it as a singleton and asks for further settings that I cannot provide. When I then try to boot, it comes up with 'missing operating system'. As a separate issue, I am now experimenting with Win 8!!
