The wiki (https://help.ubuntu.com/community/MacBookAir3-2/Narwhal) says there is a way to install from usb (http://ubuntuforums.org/showpost.php?p=10886829&postcount=320) but I can't get it to work on my Macbook Air 3,2 (the Nov 2010 revision, not the one from last week).
My goal is to dual-boot OS X and Ubuntu, but I can't get the Ubuntu installer to boot. I've tried a lot of variations on the instructions I've found, so I get the feeling I'm probably missing something fundamental.
I installed refit and used BootCamp to partition the drive. I downloaded desktop/alternate and i386/amd64 isos. I tried to follow the instructions to use unetbootin on OS X to install the ISOs to my USB drive, but neither drive that I connect appears in the "Drive:" selector when on OS X. I used usb-creator-gtk and unetbootin on an Unbuntu machine to try each of the four ISOs.
When I try to boot the Air from the USB drive, I got a few different types of failure:
gpt, single fat partition, unetbootin -> alternate amd64
result: "Non-system disk" "Press any key to reboot"
mbr, single fat, unetbootin -> alternate amd64
result: black screen, fan runs at 100% after a minute or two
mbr, single fat, unetbootin -> alternate i386
got tux with usb icon in refit
result: "Non-system disk" "Press any key to reboot"
mbr, single fat, unetbootin -> desktop i386
got tux with usb icon in refit
result: "Non-system disk" "Press any key to reboot"
gpt, single fat partition, unetbootin -> alternate i386
got diamond with usb icon in refit
result: "Non-system disk" "Press any key to reboot"
mbr, single ext4, unetbootin -> alternate i386
got diamond with usb icon in refit
result: "Non-system disk" "Press any key to reboot"
mbr, single fat, unetbootin -> alternate amd64
got colored cubes with usb and tux with usb
cubes: got grub menu, all lead to busy cpu hang
tux: "Non-system disk" "Press any key to reboot"
I also tried a few of these with usb-creator-gtk and got basically the same lack of results.
I tried these instructions (http://askubuntu.com/questions/10561/how-to-install-on-a-macbook-air-3-2-without-an-external-cd-drive) and got the same "Non-system disk" error with alternate-amd64 but didn't try all the others yet.
I tried dd'ing a disk image to my new partition as described here (https://help.ubuntu.com/community/How%20to%20install%20Ubuntu%20on%20MacBook%20using %20USB%20Stick) and here (http://ubuntuforums.org/showthread.php?t=1608823) with the desktop amd64 and i386 images, got a few different errors - once syslinux complaining "Error: No configuration file found" when the drive I dd'd from wasn't properly unmounted before bringing it to the Air, once I chose the drive in refit, refit displayed the single logo, and it never booted, and once I got an error I didn't copy down about needing a boot floppy.
Has anyone successfully booted Ubuntu from USB key on the Air? Exactly how did you prepare which image?
