Hi Goku,
Thanks for your reply, I see what you mean, and had feared that may be the case. I haven't been able to perform a repair install yet though, as the repair option wasn't available, I simply used the recovery console to try and get back some of the system files. Your point would make sense, even as a result.
I suppose I'm possibly looking for one of two things, activtaed system restore, without being able to go into the recovery console, or extract data from the HD.
Thanks again
Oliver
