Title:
  / (so /boot) on btrfs : GRUB could not be installed on /dev/sda

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

Bug description:
  I set manual partitioning :
  sda1: fat16 255MB
  sda2: ntfs 786MB
  sda3: ntfs 124.5GB
  sda5: btrfs on / 25GB
  sda6: btrfs on /home 98GB
  sda7: swap 1.5GB

  When completing the installation, I had a message telling that GRUB could not be installed to /dev/sda.
  Nothing prevented me from doing such partitions.

  I retried the same installation with the following manual partitioning :
  sda1: fat16 255MB
  sda2: ntfs 786MB
  sda3: ntfs 124.5GB
  sda5: ext3 on /boot 500MB
  sda6: btrfs on / 24.5GB
  sda7: btrfs on /home 98GB
  sda8: swap 1.5GB

  It succeeded.
