I have Ubuntu 12.04 installed on external USB hard drive.
Can I use that same installation (on same USB HDD) on Macbook Air? Can you give me some advices how to boot it?
Thank you in advance!
I am familiar with a windows enviroment, when i'm using a a windows computer, I enter the BIOS settings and change the boot sequence so it checks if it can boot from a USB device before it goes to the hard drive. As i have looked online, apparently, there is no BIOS on a Mac, but there is a program called EFI apparently, where you can change the boot order from the hard drive(or solid state drive) being first to making your external hard drive first.
EDIT: There also was a thing on the apple website that said if you press "c" during start up, it will boot from a bootable CD, DVD, or USB drive. If this works, it might be easier. MORE INFO
Sorry if this was not enough information for you, hopefully it is, but i could not test it out, as i do not have a mac.
