Personally, I have been using Acronis Disk for a long time, which is an ideal utility for any work with a hard disk. Acronis True Image 2016 software is an excellent tool for creating a full backup of all local partitions, including the system one. I also think that you can get help in this issue here on AnswerShark since many students are faced with this problem. There are more recovery options with Recuva software.
