Looks like a kernel/firmware problem that later prevents efibootmgr from working:
efivars: get_next_variable: status=8000000000000005 ** Package changed: grub-installer (Ubuntu) => linux (Ubuntu) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1519172 Title: Latest Wily install fails when installing Grub 3x in a row. Checked md5, all fine Status in linux package in Ubuntu: Incomplete Bug description: Three attempts at installing Wily alongside Trusty 14.04.1. Steps: dd /dev/zero bs=16M count=128 to ensure all previous partitions and data are gone. Boot from Trusty 14.04.1 USB drive, select erase and install. Install without errors (none I'm alerted to or aware of, anyway) Shut down - not that no updates or upgrades were performed... Reboot from latest Wily 15.10 USB. Select "install alongside 14.04.1" Installer fails when grub installer is running for the 2nd time (?). I watched it run and create the 4.2 linux kernels and initrds. Upon inspection, they appear properly installed in /boot. I'll boot manually into both Trusty and Wily and attempt to reinstall Grub so they can share it and I can choose.
