Grub Problems on Intel Mac Mini

Some time ago I had been booting Ubuntu on a Mac Mini off of the internal disk (hd0,2) with refit and legacy grub. At some point this broke after some Linux. Mac and hardware changes.

Now I get "GRUB Hard Disk Error", when refit tries to boot off the partition. Apparently that means that grub is having trouble with the disk geometry it tries to get from the bios when it goes to stage 1.5/2.

I know that the Bios emulation is still there, and Refit thinks the GPT and MBR are in sync.

I can boot off a grub cd, which then boots from (hd0,2), but I would like to avoid this step.

Any ideas on how to debug this?


Another issue is that even with the grub cd there is a limitation. From the interactive mode it only sees the internal disk. I have a usb external enclosure which grub does not see. Yet if I boot the same cd on a notebook, grub does see the same external usb disk. Of course on either the mac mini or the notebook, Linux can use the external disk once its up.
