I updated windows 10 yesterday to the Creators Update and after that my dual boot system with 16.04 can't boot to any OS showing me a black screen indicating grub rescue error. Then I tried to boot ubuntu from a USB memory and see what happened. Gparted is showing the linux partition highlighted in the image as "unallocated space", so I can't mount the partition in live mode and try to access it:
ubuntu@ubuntu:~$ sudo parted /dev/sda print | grep Table
Partition Table: msdos
Trying gdisk the linux partition is again not listed:
root@ubuntu:~# gdisk /dev/sda -l
GPT fdisk (gdisk) version 1.0.1
Partition table scan:
MBR: MBR only
BSD: not present
APM: not present
GPT: not present

I don't have much experience with linux partitions, but is it possible to recover the linux partition in this case and boot again? There is no critical data to save, the work I was doing there has been saved to git, but I would like to avoid the time consuming task of setting up the system again.
