Hi all so I have had my mid 2010 27" imac for my company since new just recently I let my son install Bootcamp to play his computer games on, just this morning when I went to boot it up it gets stuck on the loading screen with the spinning wheel I have held down the option key and ran the disk utility but it says the classic Disk utility cant repair this disk back up and reformat. I know I also should have been regularly using time machine to back everything up but haven't since I got it I have also tried to reinstall the OS but it comes up with disc locked please tell me there is a way to save the information on my mac I have a lot of important documents is there any way to get my mac going again or just save some of the information on my hard drive? I also tried the search bar before posting here so go easy on me cheers lads.
