Finally here is the output of sudo fdisk -l for my system: WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The utilįdisk doesn't support GPT. Conversely I cannot boot into Ubuntu via Refit even though that partition shows up on the Refit menu (as a Windows partition because I think Refit assumes anything that isn't OS/X is 'Windows').

In order to boot into OS/X I have to use the hardware support on the Mac by pressing the option key while it's booting and then selecting the OS/X partition, which then boots via Refit. It just hangs and does nothing if I select that. I also have not been able to boot into OS/X from Grub even though it's on the Grub startup menu. But it won't let me reinstall it any other way.Īs background information I might mention as background that I have Refit installed on the Mac side, in case that is a source of the problem because it's conflicting with or fighting with Grub over the boot sector or something like that. So I use the -force option and it does install it, but the fact that it does not go according to the instructions has me concerned that perhaps that is the source of the instability that the warning is telling me about. One problem I run into when trying to follow those instructions is that when I get to step #11 where I am supposed to run grub-install /dev/sda, it always tells me that I cannot execute that command because it would have to use 'blocklists' which are inherently unstable, and the the only way to proceed is to use the -force option on grub-install.

That always works to reinstall things, but as you can imagine, it's not my favorite thing to do and takes about a half hour each time. To do that I follow this procedure:īy following the instructions under ChRoot.

This has happened with several of the recent versions of Ubuntu, although I don't have an exact record of which ones.Įvery once in a while, after a system update with the update manager, I can no longer boot into Ubuntu unless I repair the GRUB installation manually. I have a Macbook Pro 5,2 and I've had a sporadic problem with having to reinstall GRUB after a system update.
