Yeah pointless. Even if no changes to partitioning are needed, parted still overwrites the GPT and nukes the hybrid MBR. You have to recreate the hybrid MBR post-install. > 4.

The point of BIOS Boot is to install GRUB 2's core image there. Installing GRUB bits elsewhere isn't recommended. For MBR disks, it's not recommended for core.img to go anywhere but in the MBR gap. > 5. However the hybrid MBR of the disk was cleared. So I had to setup > again the hybrid MBR with gdisk.

ReFit should find it > as I know. GRUB Legacy EFI is installed on its own HFS+ partition, this is unique to Mac installs of F17. I actually don't know if rEFIt will find it or not,but I think it does. For this to work, you need to let anaconda do it automatically. Custom partitioning doesn't work. So you first nuke all partitions from the previous Linux installation from the GPT, leaving free space. Then have anaconda use the Free Space installation type and it will create all of the correct partitions for Mac EFI boot. You'll even get a Fedora option in the Startup Disk panel in Mac OS. A small limitation is that the HFS+ bootloader partition is named Untitled in the Mac OS GUI. You can rename it if you want with no ill effect.
