This is on a six-core system, 8GB ram, win 8.1 64bit. Yesterday everything was fine. I went to shut down at the end of the day and selected 'update and shut down.' Then in the morning windows would not boot up. After some digging around it looks like the update moved my entire windows folder (which was in my C drive) to my E drive. Could not do a system restore, could not do a repair, have no backup image. Please help.
