I have trusty on a 2013 MBA 13" and ran into this exact problem... I can at least confirm that Seth's comment #17 above seems to have been the solution... installing grub-efi seems to have fixed things.
What I find interesting is that it booted fine when I first installed and then after letting it sit for a few weeks (I dual boot with OSX using rEFInd) it stopped booting, hanging in exactly the same place mentioned in the original summary. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1284085 Title: unable to boot after install on 2013 macbook air To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-release-notes/+bug/1284085/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
