Title:
  [quantal] Ubiquity fails to install grub  --> no access to Ubuntu
  after install

Status in “grub-installer” package in Ubuntu:
  Confirmed

Bug description:
  Firstly, excuse my bad english :)

  INITIAL SITUATION:
  I was trying to install Ubuntu on an Asus Vintage V7 - P8H61E. But couldn't. Finally I managed installing Fedora 17. There I booted on a LIVE USB with Quantal 64bits (because I wasn't able to boot on a LIVE with any other Ubuntu older than Quantal) and managed to get a boot-info : http://paste.ubuntu.com/1218312
  Then I booted again on a LIVE session (legacy-mode) on the same key, and began the installation of Quantal. I went through the manual installation ("Somethingelse") with these partitions :
  /, swap and /home.

  BUG ENCOUNTERED:
  I choose to install the bootloader on /dev/sda1 which is the root partition. The installation went on.
  When the install-program was configuring grub-pc, I got this message :
  "The grub's installation failed. Sorry, something went wrong. Installing the grub-pc wasn't possible at the indicated place. What do you want to do ? choose another disk where to install the grub-pc ?"
  There were different choices : /dev/sda, /dev/sda1 and /dev/sda3
  I chose /dev/sda, but got the same error message. The same with /dev/sda3.
  The other possibilities were :
  To go on without installing any grub
  To stop the installation.

  I've chosen to go on without the grub. I was warned that I will have
  to install manually the grub-pc, otherwise it wouldn't be possible to
  start Ubuntu. I said Ok. The installation went on.

  RESULTING SITUATION:
  At reboot without liveUSB, no GRUB menu appeared, and no access to Ubuntu.
  Then I reboot on a LIVE session, and manage to get another boot-info :
  http://paste.ubuntu.com/1218341

  WORKAROUND:
  Then I started Boot-Repair again from liveUSB, and chose "Recommended repair" (which installed grub-pc into /dev/sda), which succeeded, and provided another boot-info :
  http://paste.ubuntu.com/1218343
  I rebooted without liveUSB, and succeeded accessing the installed Ubuntu.

  FURTHER INFORMATIONS:
  Then I tried to install the updates, but the update-manager stopped at "configuring the grub-pc". After a while, I wanted to quit the update-manager, but it didn't quit, it crashed.
  I reboot on LIVE session, got another boot-info :
  http://paste.ubuntu.com/1218378
  I used boot-repair to... repair and get this boot-info :
  http://paste.ubuntu.com/1218383
