[Bug 745960] Re: Cannot boot GRUB on Intel Mac after installing to LVM

[Dirk Räder]

Hi Chad,

this issue has been reported on several machines ranging from Mac thru
x86/x64 VMs to x86/x64 physical machines. I experienced it on a
Samsung netbook and different VMs Virtual Box on two different hosts.
On both hosts inside the VMs, this issue doesn't occur any more.
Regarding the netbook - I simply don't have a disc image to restore
its current state, else I would already have tested it.

Could you take the time and verify the bug is fixed on your Mac, then?
Thanks!

  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.
