My desktop computer froze up and I had to restart it. I was opening a program and had to ctrl+alt+del to close the program. Then it said windows explorer wasn't reponding, so I restarted the computer.Then it wouldn't go further than telling me Windows is loading. I tried Safe Mode, Safe Mode with Command Prompt, and the couple of other choices. None will get me to the Windows screen. I heard about going in through Linux. Not really sure about that but the data I have on the computer I really need. Any suggestions??
