[Bug 959446] Re: Ubiquity failed to install GRUB on a EFI & non-GPT system with pre-installed Windows

[YannUbuntu]

** Description changed:

  Initial situation: HP Touchsmart 520, 64bit 4GB, pre-installed Windows7
  (on sda1 and sda2), non-GPT disk, 356Go unpartitionned space after
  Windows.
  
  Installed Ubuntu 11.10 via automatic installer. Ubiquity gave no errors
  nor warnings during install.
  
- After install: 
+ After install:
  - after reboot, no access to Ubuntu. PC boots directly to Windows.
  - see attached files: /var/log/installer/syslog  ,  /var/log/installer/partman  and debug files,
  - see BootInfo summary created via Boot-Repair: http://paste.ubuntu.com/890361  (apparently boot is in EFI mode)
  - Ubuntu contains /boot/grub/grub.cfg , but no core.img and no grub.efi
  - MBR has not be modified (it contains no GRUB)
+ 
+ 
+ WORKAROUND: purge and reinstall grub-pc via Boot-Repair, with nomodeset option, allowed to obtain GRUB menu with access to Ubuntu and Windows. See resulting BootInfo: http://paste.ubuntu.com/891331
