14.04 boots fine on my laptop with secure boot enabled. Never had an issue with it. 14.10 will not. The laptop complains there is no boot disc available.

I have tried updating 14.04 to 14.10 without success. I have formatted the SSD and recreated the EFI partition (512MB), Swap (4096MB) and the root partition (200GB), formatted as normal to BTRFS.

A 14.10 USB installation stick will boot but but the SSD will not.

The BIOS settings are unchanged between versions.

I have now put 14.04 back on and all is well, but want to upgrade.

Can anyone help?

this might be related to this bug on launchpad. If yes, you could fix it by

  • booting with refind
  • installing an older version of efibootmgr (or compile & install the latest).
  • re-create the bios entries with sudo update-grub
  • examine bios entries with efibootmgr -v. Assure, that there are no entries with the same key.

Hope, that helps!

This is a link to hardware 'certified' to work with Ubuntu. Samsung isn't even on the desktop or server list of hardware. If you got 14.04 to work it was just random good luck.

More specs on your laptop for other users.

Samsung is a pretty big provider of PCs, smartphones and tablets, I'm not sure why they aren't certified. Perhaps they just didn't ask.

14.10 is too new so they haven't gotten 14.10 to work with Samsung Series 9 in all cases. Here's a page about 14.04 working with the Series 9.
