I'm trying to install Ubuntu 12.04 on a Macbook Air 1,1. I made a live USB stick using Penguintosh (the more common methods failed). Now, the regular amd64+mac installation hangs the moment I click on the installer, with an endlessly spinning cursor and nothing else, although the live desktop works fine before that. I tried suspending the computer to unfreeze the hard disk, as recommended in one place, but that doesn't solve the probblem

The alternate install gives me a grub prompt and nothing else. Typing "boot" at the command line gives the response "error: no loaded kernel".

Can anyone help with either the regular or the alternate install?

Windows is not installed on this machine, although there is a backup install of OS X. I don't think bootcamp is installed. – jaia Nov 11 '12 at 5:32

You marked your USB bootable . you should only extract ISO to USB without drive formatting .

On a Mac? And then what? You have to boot from the USB to install Ubuntu from it. Also, by "extract iso", do you mean dd it to the USB drive? I tried that and it didn't work. – jaia Nov 11 '12 at 5:35
