Arch by default in a dual-boot Macbook [Solved]

MGu3l · 2015-08-06 20:56:57

Hey everybody, I'm facing a little problem here with my macbook. Until yesterday Arch was the OS loading by default but by mistake I chose OSX in the control panel and now it is the default OS.

The common behavior was: gray screen [which is the mac boot loader], by default it chooses /sda1 and it loads grub, then I choose Arch].

I'm not using rEFIt or other boot sowtware, just the default Mac loader. I guess there's a file I should edit in the /boot/efi but I'm afraid of wrecking something.

Any help will be highly appreciated.

Setting the intended partition using efibootmgr should work, I think.

Just in case you don't know this yet:
You can start the Mac boot menu by hitting and holding the option key (alt) right after the startup chime.
However then choosing Arch respectively grub will not make it default, as far as I remember.

typo, I checked efibootmgr and this is what I found:

BootCurrent: 0000
BootOrder: 0080
Boot0080* Mac OS X
Boot0082* 
BootFFFF*

according to this I should edit BootOrder to 0082* in the first place, but I have two questions:

1. how can I know the label of the other boots? [one is Arch and the other one OSX's recovery]
2. how should I reorder this?

I readed the help but still is a little bit confusing and I'm afraid of breaking something... Linux in a Mac is such a pain in the ass.

Respiranto, I know I can do that and that's exactly what I'm trying to avoid, I know is not a big deal but sometimes I forget to press the alt key so I have to wait for OSX to boot, restar and press alt again [and believe or not, I can forget again to press the Alt key].

Gladly, it seems Typo's idea is working... I tried using the command

efibootmgr -n FFFF

[which is weird, I thought Arch would be 82 partition].

I'm going to test again to see if it works, and then make the change permanent by using the same command with -o, fingers crossed!!

EDIT: Solved!! Thank you so much tyco, your idea worked perfectly!!
