[Bug 908203] Re: GRUB2 fails to install on Lenovo IdeaPad V570-1066AJU

[Cory Flick]

Same laptop. Ubuntu 11.10 and 12.04 beta both will go through their
installation routines from desktop livecds just fine, then fail to boot
at all from the hard drive.

Linux Mint 12 will install just fine from its livecd, then the
installation will boot just fine from the hard drive upon reboot (
everything works as expected ).

There is something weird about this Lenovo model's bios and hard disk
related to GPT partition table vs ms-dos partition table, and it makes
life difficult for the Ubuntu installer to correctly figure out whether
to install grub-pc, grub2, or grub-efi, IF anecdotal Googling about this
issue is to be believed.

IIRC, the Mint installer is just a tweaked version of Ubuntu's. I have
to believe that if the Mint folks can hit on the right secret sauce, so
to speak, so can the parent distro.

  GRUB2 fails to install on Lenovo IdeaPad V570-1066AJU

Status in “grub2” package in Ubuntu:
  Confirmed

Bug description:
  New Lenovo IdeaPad V570-1066AJU Laptop with Windows 7 preinstalled.
  After installing Ubuntu 11.10 and restarting, the laptop goes straight to windows 7, without loading grub.

  GRUB reinstall via Boot-Repair shows that GRUB2 install is performed without error nor warning, but as a result the MBR remains unchanged :
