Title:
  Grub EFI partition broken when installing 14.04 with 13.10 installed

Status in “ubiquity” package in Ubuntu:
  Incomplete

Bug description:
  13.10 was already installed and my working version in its own partition (dev/sda3)
  14.04 beta 2 was newly installed into its own partition (dev/sda4)

  System was left unbootable and broken because Grub could not be found
  at boot time.

  To try and fix the problem I used the boot-repair-disk-64bit.iso
  (dowloaded from: http://sourceforge.net/projects/boot-repair-
  cd/files/latest/download?source=recommended). This was apparently
  updated last for 13.04. The contents of README.diskdefines are:

  #define DISKNAME  Lubuntu 13.04 "Raring Ringtail" - Release amd64
  #define TYPE  binary
  #define TYPEbinary  1
  #define ARCH  amd64
  #define ARCHamd64  1
  #define DISKNUM  1
  #define DISKNUM1  1
  #define TOTALNUM  0
  #define TOTALNUM0  1

  The tool was not able to run completely on its own with the
  "Recommended repair" option which in the past had worked properly.
  Instead, it gave me a list of commands to run in a terminal which I
  ran. The commands said they worked and the repair tool completed
  without error but the system could still not boot afterwards.

  How I fixed the problem:

  Booted Live/CD
  Deleted EFI and 14.04 partitions
  Recreated EFI partition
  Reinstalled 14.04

  Apparently, the same can be accomplished from the command line but
  didn't see the posting before reinstalling.

  Upon further investigation, it appears that 14.04 uses a newer version of Grub? 

  Although, the source of the problem may not be related to Ubuntu
  specifically, because EFI was introduced by Microsoft, it nonetheless
  reflects badly on Ubuntu when the user expects the installer to simply
  just work. These kind of issues really turn off users to Linux since
  they are a headache and eat up so much time.
