Two days ago I was doing a defrag on my hard disk, but a power failure screwed the process. After the power failure the computer won't boot. It says something like: "Error, hal.dll is missing or corrupted". After that I went like crazy because the documents there are really important to me, so I tryed many things: boot in safe mode, overwriting that file... but none of them worked.
After that, I reintalled the OS and I have tryed to retrieve my documents from the previous installation but when I try to access the "My Documents" folder, it says: "Unable to access folder. Access Denied". Can somebody help me retrieve that information please?
