Hello everyone,
A friend gave me his old macbook pro (end of 2011 I believe). I had to change the hard drive since the old one was broken.
I tried to install Ubuntu with a bootable usb drive, but it won't boot. I even try to install windows 10 and MacOS Sierra, but same result. I heard something about a secureboot that is installed by default on every Macbook. Could it be the problem ?
I'm sorry if my questions are silly, I am usually just an user of our main computer at home (and English is my second language).
Any idea ?
Thnaks !
