[Bug 1026270] Re: grub-installer failed to install grub in ubiquity installer

[Phillip Susi]

This actually isn't a duplicate.  This error is because you tried to
install grub to a partition instead of the MBR.  This requires the use
of block lists, which is prone to breakage on most filesystems, and
outright impossible when /boot is on btrfs.  You need to install grub to
the MBR instead.

Title:
  grub-installer failed to install grub in ubiquity installer

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

Bug description:
  When trying to install grub to Ext4,3,2 and Btrfs, the installer
  showed "Executing 'grub-install /dev/sda' failed. This is a fatal
  error.". Installing to a dedicated Ext2 /boot partition fails. I
  didn't have this problem for 12.04 but I have it in all  ubuntu
  12.04.1 based installations.
