So I wanted to open a psd file in Gimp, whole computed froze had to power off (case doesn't have a restart button, dumb, I know).
So after powering up I was stuck at the Grub screen. So I set the root, linux and initrd and booted, and run this command after the first successful boot
$ sudo update-grub2 followed by
$ sudo grub-install /dev/sda i got a success message on both account but after I restart PC I am always stuck in the Grub recovery and have to do the whole process again.
Any ideas? Ubuntu 18.04 LTS.
