I recently installed some updates on my laptop (running windows 8.1) which required a restart. Upon restarting however I received the following error message: wheauncorrectableerror. I tried to start up in safe mode, but to no avail, I still got the same message. I tried to restore the system to before the update, but that failed. I ran command prompt with chkdsk and it failed stage 3, with the following error: "7 data files processed. Errors detected in the uppercase file." I'm not sure what that means. Is the problem with the hardrive? If so how can I fix it? Really just want to get the system working again. Any help would be greatly appreciated!
