I have the same problem to boot my macbook pro retina Early 2015. When
I try to boot the system it gets stuck in the "loading initial
ramdisk" stage. Then, it reboots automatically, and sometimes it
passes this stage or get in a reboot loop. I used the guide in [0] to
boot in efi mode.

However, If I just boot directly by using the Startup Manager[1] the
"loading initial ramdisk" problem disappears.

I have tried the following to solve the problem without success:

1) nomodeset in the grub menu.
2) update-grub; update-grub2.
3) update-initramfs -u
4) Reinstall all /boot/efi from scratch.

However, as already stated, launching the grub menu from the Startup
Manager works just fine.
