Running El Capitan on a 2006 1,1

[jrazor]

Hello to all...
Hopefully I posted this correctly...

Hoping that no one else is having this challenge, but would love to know what I am doing wrong...
Trying to get El Capitan running on a 2006...
Have used a 2008 to upgrade OS X from 10.7.5 to 10.11 El Capitan on the 1,1 hard drive...
When trying to setup Pike's Alpha have some interesting challenges...

When I do to the suggested methods of changing the file flags on "boot.efi" I get
"chflags is not permitted" or something similar (sorry getting a bit tired and frustrated)

Since the file "boot.efi" resides in the folder /System/Library/CoreServices I have been using this command in terminal...

sudo chflags nouchg /System/Library/CoreServices/boot.efi

This is from the "Guide for Installing Yosemite on a Mac Pro 1,1 or 2,1"
Any ideas would be appreciated

I just literally copied the new boot.efi onto the 10.11 drive using a different mac from the finder. (or you can just boot from a different drive if you have one)

You need to unlock the boot.efi in coreservices first though.

You also need to replace the boot.efi from hidden folder "usr/standalone" too.

Just hit cmd-shift-g and type /usr to get into that folder.
