Hello,

I'm now using debian wheezy on my macbook pro under el capitan.
It's not the most usefull possibility but i use a refind bootable key to launch it each times.
I could install directly refind but i do not want to have to choose at each start the os i want, and i feel more comfortable like that.

When "alt" option at start, i should be able to put some information in the efi folder of my debian partition and bless it or something like that to permit to choose it directly. Or, install refind on a partition to boot on refind as it would be on windows and after modify refind config files to automatically boot on my debian.

I'm looking for some working return for you guys as it will be easier to have an already working way that to try a lot of option who always have to be configured with a little hardness.

If you need help to install linux on your retina macbook pro , feel free to ask.

Thanks

I believe you have to disable System Integrity Protection (SIP) because otherwise you won't be able to see other boot options in El Capitan.

i disabled it. it's not the problem. actually i don't have any problem, i want to know how to do it.
i guess the easiest way would be to install refind as a small booting partition of the disk, and then refind will find the linux partition and the bootloader.
mac is so dumb when it start to go other way than having to embeded os ...

I had a really hard time understanding your post. But I think what you are asking is that you want Debian to be the default operating system that boots up, without having to select it first via holding down ALT, using Refind, or any other manual method.

It is possible to set the boot order. See "Using efibootmgr to Adjust Your Boot Priority" at the following link:
http://www.rodsbooks.com/refind/bootcoup.html

Although the instructions are intended to make Refind the default boot, you can just adjust the command as needed to make Debian your default boot.
