what causes the system failed to perform the requested operation there is an unknown error error when trying to set up quick connect??

I am using a GA-K8NS Ultra-939 MTB for a bare metal build. I have had it up and running for ages running 5.2 I think but the other week had cause to down it and that was it it wouldn't boot.So a rebuild was neccesary At first it stated there were no disks insatalled. Formatted all disks,now I am in a cycle of "Migration" and "Reinstalation" without going any further,sometimes it says the file might be corrupt.I have tried a manual build as well all without success. Any idea's??
