Fix : Ubuntu Boot error – Boot device not found (after partitioning)

Posted on by Sreekumar Kj

Problem: Ubuntu gives the message “Boot device not found” after partitioning using Gparted (done from a usb instance).

Reason : Unknown. Could be that no partition was mapped to /boot.

Fix: Open terninal – Run these commands

  1. sudo mkdir /media/fix
  2. sudo mount /dev/sda2 /media/fix(replace /dev/sda2 by your drive name.)
  3. sudo chroot /media/fix su
  4. apt-get update
  5. apt-get upgrade
