[Bug 1080058] Re: Unable to install on Ubuntu with EFI and GPT, but GPT disk is not the boot disk

[Calabacin]

After following <a href="https://help.ubuntu.com/community/Boot-
Repair">this guide</a> I was able to finally boot grub (apparently it
only worked if grub was installed in partition /dev/sda5).

I still cannot boot Ubuntu, it reboots before showing any information,
and because grub does not support USB keyboards I cannot even choose to
start Windows.

But I guess that this problem was 'solved'.

Title:
  Unable to install on Ubuntu with EFI and GPT, but GPT disk is not the
  boot disk

Status in “ubiquity” package in Ubuntu:
  New

Bug description:
  I have a computer with several disks and with Windows 7 64bit
  installed. The boot disk (sda) is an SSD and the home, tmp, and swap
  partitions are in partitions in a 3TB GPT disk. During install I chose
  manual partitioning, and created all partitions, both on the SSD and
  on the GPT disk. One weird thing is that I created partitions on the
  GPT disk (mix between MBR and GPT?)

  When trying to install, the cd would not boot properly, so I chose
  EFI-cd-boot from the bios and that worked perfectly.

  Install did everything flawlessly, and then, on reboot, grub does not
  work. It says it cannot find i386-pc/normal.mod

  I have tried from the boot cd to execute this command:
  sudo grub-install /dev/sda

  But I get this error (tried with sdb and sdd but got this same message):
  Path `/boot/grub' is not readable by GRUB on boot. Installation is impossible. Aborting.

  I cannot boot Ubuntu, and my Windows 7 is unbootable. I can access all
  disks from my boot-cd, so I can send any file you may need.

  I'm attaching /var/log/installer/syslog found on the installation disk
  (/dev/sda1), I am getting this file and sending this report from the
  Ubuntu boot cd (no other way to use my computer at this time). If you
  want me to install again, and then, without rebooting, get the logs, I
  can do that without problem.
