  1. I just want to share my solution as I just fixed same problem for me. I am using ubuntu 14.04 x64, however native instead of booting in virtualbox.

    Tl;dr: sudo dpkg --configure -a solved my problem.

    I tried manually booting using mount /boot/efi but it exited with error 32: mount :wrong fs type, bad option,bad superblock... It asked me to check dmesg | tail There I found that my error is because: FAT-fs (sda2) : IO charset iso8859-1 not found After googling this error I realized that my kernel does not proberly boot fat systems. Finding that another person cannot mount fat filesystems as well, and the answer to his question was to reload kernel using sudo apt-get install linux-generic. When I typed this command, I had an error: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct this problem. So I did and it reloaded lots of settings including grub, and I saw that it can mount /boot/efi from now on either terminal and while booting ubuntu. Just posting this if anyone has the same problem, hope it may help.

  2. Try to open /etc/fstab and watch inside the UUID really matching with the sudo blkid command in a Terminal. In other way:

    1. Do sudo blkid in a Terminal. See the right UUID of the /boot/efi partition.

    2. Open /etc/fstab in a Editor (eg. sudo gedit /etc/fstab).

    3. Correct the UUID of /boot/efi partition in /etc/fstab and save the file.

    4. Reboot your machine and everything should go right.
