Hello,
I have windows 8.1, which got corrupted due to missing or deletion of boot code.
So I used automatic repair by inserting the OS DVD and booting it.
After repair, the OS got started normally and my data of all primary partitions got recovered.
But data of logical drive didn't recover & in disk management, it shows the free space instead of my logical drive. Also another primary partition of around 7GB created with the name of PBR Image.
Now how to get back the data of logical drive???
