To use the "legacy BIOS" style boot, you need:
- setup an MBR (ideally you have less than 4 partitions, so you can
have a simple MBR with one pseudo-partition which is the "EFI
protective" thingy and then the other partitions as before).
You can set such an MBR without having to fully reinstall
or repartition. rEFIt used to come with a tool that did that, IIRC.
- install the non-EFI grub on your disk.
- potentially tell your Mac explicitly to use this boot method.
A tool like rEFIt can be used (rEFIt is old, it's been superseded at
least by rEFInd and probably others by now but I haven't kept up, sorry).
