Install "TestDisk" - this does the above and more.
The usual virus will try to change the MBR, but "MyDocs" runs "ext2" that is fully journalled. Load the journal, and scan the entire filesystem.

Drop Windows - this does not know about the file system, it can easily destroy it.
If the MBR has been modified, loading the previous value is the only way forward You loose the last second or two... The typical error is that the file system tye is unknown. List the types - look for "ext2" - which should be used.
If you just get hold of the journal master block, TestDisk will restore your entire "MyDocs" - also the ._Trashes directory. Use your PC to learn aout Linux / Unix commands. Good luck!
