[Bug 745960] Re: Cannot boot grub after installing to LVM

[mbudd]

I have this problem on Dell Optiplex 980 using the BIOS raid. 10.10
worked ok, reboot after upgrade to 11.04 fails. Noticed the BIOS raid
status was Initialise when it should say Normal. Another identical
machine here also had intermittent success, but after upgrading BIOS
from A01 to A08 it works about 4 out of 5 times. Mine is hard failing
even after the BIOS upgrade.

Title:
  Cannot boot grub after installing to LVM

Status in Release Notes for Ubuntu:
  New
Status in “grub2” package in Ubuntu:
  Confirmed
Status in “grub2” source package in Natty:

Status in “grub2” source package in Oneiric:

Bug description:
  Binary package hint: debian-installer

  TEST CASE:
  http://testcases.qa.ubuntu.com/Install/AlternateEncryptedLvm

  I'm using kubuntu-alternate-amd64+mac.iso from 2011-03-29.1 on a
  MacBookPro6.2

  The installation runs as expected. No errors are reported. After
  rebooting, grub does not load. It's not that grub does not load linux,
  but rather that the hardware never passes control to the grub menu. It
  stays at the grey mac boot screen, as if there were no operating
  systems. Holding 'Alt' during boot, which is the standard way to boot
  when only Linux is installed on the Mac, offers no partition to boot.

  Installing the same system in the same manner without an encrypted LVM
  works fine. I did not test installing an unencrypted LVM.
