Hi; I upgraded Windows 10 and my system lost a partition with dual boot using Ubuntu during the process; I don't know how the use Test Disk; my computer is a Dell; when I search for disk, two appears; one is called C: and the other dev/sda.
This is whats on both disks:
And this is the search I did in dev/sda where a Linux partition appears:
I need to recover my partition of Ubuntu and get back grub to have the dual boot; when I was upgrading the system, I used a disk to reinstall grub and continue with the upgrade of windows because of the reboots; after the upgrade the system just entered directly to Windows; I used a boot-repair live cd thinking it will recover grub; but there was no Linux partition.
I hope someone can help me.
Dual boot lost after upgrade.
