I had the Windows error that the following file is corrupt or missing C:\WINDOWS\SYSTEM32\CONFIG\SYSTEM and had tried every possible solution to remedy this that I could find with no luck. So I tried Linux, but when I click on my HD it tells me it cannot be accessed and to try chkdsk /f then reboot twice. I tried this in the Windows repair console and was told that that is not a command. If anyone can help me I'd appreciate it.
