I had accidentally lost my partition. I do not know how that happen. Does this can be due to broken partition table. What happen here is that the pc shutdown suddenly. And then on reboot there was nothing. I am using Linux Mint. This is the first time it happened that I lost my partition. I had updated my operating system for better functionality. If I loose everything then it is really a matter of despair. I have lots of data store on that especially the pictures. I wonder if you can recover Linux partitions, when I bring up the boot menu choice of Linux that I had was the GRUB default because the last system was installed.
