How can I install Fedora Linux on a MacBook Pro, Model A1150? I performed the following steps:


Formatted a USB Flash Drive as: FAT32
Copied the Fedora Live ISO image to: /efi/boot/boot.iso
Copied ISO 2 USB EFI Booter for Mac to: /efi/boot/boot.efi


I then inserted the USB Flash Drive into the MacBook Pro, pressing the  option key directly after turning it on. However, after selecting the disk to boot from, it only booted to a grub prompt.

What else do I need to boot this Fedora Live ISO image from a USB Flash Drive?
I see in your question, per the second and third bullet points, you are attempting to boot the USB Flash Drive via UEFI.

There are two MacBook Pro's with Model Number A1150, both having the Model Identifier MacBookPro1,1 with one of the following Processors, Intel Core Duo (T2400, T2500, T2600) and Intel Core Duo (T2500, T2600) on the 15" Glossy Display.


All three processors listed use a 32-bit Instruction Set.


Therefore, since UEFI booting is only supported with the 64-bit release of Fedora and the MacBook Pro model A1150 has a 32-bit processor, you will need to download and burn a 32-bit version of Fedora to optical media (CD/DVD) and attempt to boot from it, if that too is even possible.
