Hi. I have an HP Pavilion dv6810 running windows vista sp1. When I shut it down this morning, I accidentally unplugged it before it completed shutting down. When I restarted it this evening, it performed a startup repair and restarted. It will begin like normal, but then it will stop on a black screen with only mouse control ability. Since Vista came with my laptop, I tried downloading the repair ISO on another machine. I burned it to a disk and ran it on my machine but nothing has changed. The machine will not start in safe mode and will not let me do a system restore (it says I have not made any restore points which I know is untrue). Any suggestions would be appreciated.
