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

[Calabacin]

** Description changed:

  I have a computer with several disks and with Windows 7 64bit installed.
- The boot disk is an SSD and the home, tmp, and swap partitions are in a
- 3TB GPT disk. During install I chose manual partitioning, and created
- all partitions, both on the SSD and on the GPT disk.
+ 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?)
  
- Install did everything flawlessly, and then several things have happened (tried installing several times):
- 1.- grub was installed but ubuntu would reboot during the early boot
- 2.- Reinstalled and managed to boot, but then the next day it would reboot just like in step 1 (I hadn't tried to boot after doing all updates before)
- 3.- Reinstalled. Now grub would not work. Tried to fix that by booting to the CD and installing grub on almost all disks. It worked, but then Ubuntu would reboot as before
- 4.- Reinstalled one last time, but now grub does not work. It says it cannot find i386-pc/normal.mod
+ When trying to install, the cd would not boot properly, so I chose EFI-
+ cd-boot from the bios and that worked perfectly.
  
- I cannot exit step 4 now, and my Windows 7 is unbootable. I can access
- all disks from my boot-cd, so I can send any file you may need.
+ Install did everything flawlessly, and then, on reboot, grub does not
+ work. It says it cannot find i386-pc/normal.mod
  
- When trying to install, sometimes the cd would not boot, and I would fix
- that by choosing EFI-cd-boot from the bios. Some other times I did not
- choose that but it booted sometimes (maybe kept that boot config).
+ I have tried from the boot cd to execute this command:
+ sudo grub-install /dev/sda
  
- I have installed lots of Ubuntus and have found almost all posible
- problem, but this is new to me and I cannot figure out how to fix it.
- I'm thinking it may be related to using a GPT disk, but I'm not sure.
+ 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.
