Hello, I have been using Boot Camp and Windows 7 Enterprise 64-bit on my rMBP 2012 for two years. Few hours ago, when I tried to launch Windows, I got a message saying that Windows needed to repair the system. After awhile, I got another message saying that the system could not be repaired. However, I could continue. Once Windows was launched, it was like a newly installed Windows. All my programs and data are gone. The except is that in Documents, there is a folder Autodesk with some files, an empty CrashDump and an empty NativeFus_Log. What happened? Is there any way to return to the system before the problem started? I am running VMware Fusion 5.0.4. Thanks.
