- On some systems, GRUB2.00 fails to install on the MBR  (but shows no

+ When grub-efi but no grub-pc, grub-install /dev/sda fails to install on the MBR but reports success.
+ It should report an error instead.
  
- 2 examples:

  1) on 12.10 http://askubuntu.com/questions/224857/ubuntu-12-10-windows-8-dual-boot-tried-boot-repair-dual-os-option-not-show
  2) fails with 2.00 , worked with GRUB1.99 worked: Bug #1087153
