Title:
  GRUB , UEFI and software raid issue

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

Bug description:
  Release:        11.04
  After installation of 11.04 ( server or alternate CD ) MBR has no GRUB. Chroot method did not help., 
  root at ubuntu:/# sudo grub-install /dev/sda
  Installation finished. No error reported.
  but MBR has no boot after.
  I found only one way how to fix:
  1) Boot from LiveCd
  2) apt-get install -y grub-pc
  ubuntu at ubuntu:~$ sudo chroot /mnt
  root at ubuntu:/# apt-get install -y grub-pc
