I love OS X a lot, but I tend to like to change things around.. I want to know what would happen if I ended up removing my OS X partition and replacing it with a Linux Distro. I will not be dual-booting or using a VM. Will I be able to re-install OS X afterwards? Or would I have to somehow re-install from USB? Or perhaps the recovery partition, if left untouched, can be used to re-install OS X? So, first part is whether or not I can undo it if I don't like the Linux distro. Second thing, I don't like GRUB, but apparently I can't use that anyways since of EFI. What boot loader would I be using? I believe the boot loader looked much like the OS X boot loader when you hold Alt. This is all on a Macbook Air 13" 2014.
