Triple Booting on an MBP

[Wilco]

I'm trying to get a triple-boot setup working with rEFIt and OSX 10.6.5/Win7/Ubuntu 10.10.

I'm finally to a point where rEFIt shows a OS X, Windows, and Linux option but the Linux item boots up windows. I just finished booting the live CD and installing grub on the ubuntu partition, but rEFIt is *still* booting windows with the Linux menu entry (and no new entries have appeared since the GRUB reinstall).

Here's what the rEFIt partition inspector is currently showing - can anyone spot any problems?

Note: Currently I have 5 partitions (OS X @ 60GB, Win @ 120 GB, Ubuntu (swap) @ 2 GB, Ubuntu @ 58 GB, and a general storage partition (formatted in OS X's HFS).

I can't offer much help about your partitioning since I've not used it.

What might be happening is that if Grub2 can't boot a selection because the menu number/name is out of range it will boot the previous one (e.g. if you pick 10 and only have 5 entries, it will boot #5).

It could be that it can't boot Ubuntu so it drops down the next available, which in this case would be Windows. Just a guess.

Posting the grub.cfg file or the contents of RESULTS.txt from the boot info script found here (http://bootinfoscript.sourceforge.net) may be useful to someone who understands your system.
