I'm trying to create a bootable USB key with Linux (debian) and that can be booted on Macintel hardware.
I have read that MAC's EFI can only boot GPT GUID formatted disks. I'm desperately trying to find a good tutorial which explains how to create such a key.
Here what I have done so far:
- create a GUID partition on te key using Linux GNU parted
- create a HFS+ or ext3 partition on the key, with the boot flag on
- install a Linux .iso with unetbootin
While all steps were successfull and in some cases I could even boot on a PC, the step of booting on Macintel software failed (on a macbook).
I need to precise that I holded the "alt" key while booting the mac and the only visible bootable disk was the hard disk.
PS: I have tried with rEFIt as well. In one case I had a "Windows" icon but it then failed to boot with a message like "no system found"
Edit: This is a rather old question, I haven't tried for a while, maybe today it is just a matter of running dd to copy the iso, but it did not work 5 years ago. I'm going to try with a recent macbook and linux iso
