[Bug 1385932] Re: Unable to boot 14.10 on Dell E6430

[Chris Coulson]

Ok, same behaviour with the latest firmware.

I've managed to get my machine to boot now by doing the following:

- Resetting the firmware on my laptop
- Booting to a 14.04 live install
- chroot'ing in to my install
- Downgrading shim + shim-signed (to 0.4-0ubuntu4 and 1.6+0.4-0ubuntu4 respectively)
- Running grub-install

One thing I've noticed is that "ubuntu" is now listed  in the boot
sequence screen of the Dell settings, whereas it wasn't listed when I
first encountered the issues with booting (the boot sequence screen was
completely blank)

Title:
  Unable to boot 14.10 on Dell E6430

Status in “shim” package in Ubuntu:
  New

Bug description:
  Yesterday morning, I tried to power on my laptop in the departure area
  of the airport, to be greeted with "No bootable devices found"
  message. After initially assuming that my SSD had failed, I realized I
  had an old bootable USB stick in my laptop bag with Raring on, which
  booted ok and allowed me to access the contents of my SSD. I ran fsck
  on it, and it didn't find any problems, and the SMART status appears
  to be ok.

  After arriving back home, I created a bootable 14.04 USB drive, which
  also booted fine. I then created a bootable 14.10 USB drive, which
  failed to boot ("No bootable devices found"). What's worse, after
  trying to boot 14.10, my laptop would no longer boot any other USB
  stick. Fortunately, restoring the defaults in the Dell settings
  appears to clear everything and allows me to boot 14.04 from a USB
  drive. However, attempting to boot 14.10 again ends in the same way
  (unable to boot anything else).

  This behaviour is fairly repeatable - I've tried it several times now
  and the result is always the same.

  Utopic did work fine before and during the sprint. It seems that shim
  got updated midweek, but Saturday morning was the first time I powered
  off my laptop since it was updated.

  My laptop is configured to use secure boot. The only version number I
  could find related to the firmware is the BIOS Version (A09)
