[Bug 340429] [NEW] Unable to install grub to MBR with LVM root device

[Robert Sander]

Public bug reported:

Binary package hint: grub-pc

The system (amd64, Ubuntu 8.04.2) has one hard disk with 3 primary
partitons:

/dev/sda1 ext3 /boot
/dev/sda2 lvm
/dev/sda3 ntfs

The LVM has 3 volumes:

  root    system -wi-ao 15.00G
  swap    system -wi-ao  1.00G
  tmp     system -wi-ao  2.00G

/dev/system/root ext3 /
/dev/system/tmp ext3 /tmp

grub legacy says:

root at quidde:~# grub-install '(hd0)'
/dev/mapper/system-root does not have any corresponding BIOS drive.

grub-pc says:

root at quidde:~# grub-install '(hd0)'
grub-setup: error: Can't embed the core image, but this is required when the root device is on a RAID array or LVM volume.

lilo was installed first from within the Ubuntu installer.

How do I install grub to the MBR?

The exact same disk layout works without any issue on i386 Ubuntu 8.04.2.
Is there any difference in the grub packages for amd64 and i386?
