When starting a disk with ubuntu (I don’t remember which version, but not older than 16.04)

there was an error

Minimal Bash-like line editing is supported. For the firs word, TAB list possible command completions. Anywhere eise tab list possible device or file completions grub>

Began to do the instructions as here: https://help.ubuntu.ru/wiki/%D0%B2%D0%BE%D1%81%D1%81%D1%82%D0%B0%D0%BD%D0% BE% D0% B2% D0% BB% D0% B5% D0% BD% D0% B8% D0% B5_grub

Booted from a flash drive.

At the command sudo fdisk -l displays this

By the command sudo mount / dev / sda2 / mnt

displays

 mount: special device /dev/sda2 does not exist

Help.

  • Is there a typo in the description of the problem? you mount sda1, and an error on sda2. - mikewoe pm
  • corrected typo - Rupert Smith
  • grub is written on the boot partition, in your case it is sda1. In this article there is no separate dedicated section for it, so the root is also mounted. In general, try to use Boot-Repair, since he will do all of the above for you - mikewoe
