>I'm trying to install Fedora (dual-boot) on a brand-new MacBook Pro.
I have a somewhat older one, but it's 64 bit EFI, so it's probably similar enough. I did not try this on Fedora 14, but I had the exact same problem with Fedora 13 and Fedora 15 (since I used Preupgrade and was also pleasantly surprised when it worked.)

Boot camp interfaces with the Mac's BIOS counterpart (sorry don't remember what it's called,) but because of the differences between MBR and GPT partitioning, only four partitions are allowed in a MBR/GPT hybrid format. Fedora was being "clever" and made the Fedora partition bootable; what you need to do is turn the boot flag off and then let the bootloader work it's magic.

You did actually manage to install it, it's just getting conflicting signals, since the Fedora partition is set to be bootable. This should work whether you keep rEFIt on there or not. First insert the live CD again, make sure that you've synced the partitions, then run the program 'parted' from the command line as root, like so:
parted
toggle 3 boot
quit
shutdown
then start Fedora exactly as you described. Because: I was able to use rEFIt with Fedora 13 quite easily, but Fedora 15 created an EFI partition of it's own and I couldn't log in via rEFIt (though it logged in via the Mac's EFI -- with the 'option' key -- perfectly.) It may be that it's created a 5th partition or "hijacked" the mac's EFI partition.

Hope this helps, please tell me if there's something else or if I made a mistake with the mailing list, I'm not quite sure of the conventions.
