Boot into the system in UEFI mode failed.. Why does 0.3 support UEFI but 0.3.1 doesn't?

Bug Reports:
0.3.1 UEFI / Secure Boot support incompatible
Freya UEFI install boots to grub prompt
I can't boot into my system after a fresh install for 0.3.1 in UEFI mode

  • Thumbs down doesn't solve any problem, the bug won't go away. – JulianLai Sep 4 '15 at 13:18
  • I have the same issue. Can't boot Elementary OS in UEFI mode after clean install. – user2276 Sep 4 '15 at 22:06

  • I dunno. Haven't activated Uefi on my system. Running here Linux Mint and elementary OS in Bios mode. If you don't use Windows I would suggest you to change your system to Bios – peppermint Sep 5 '15 at 8:23

Update

elementary OS Freya 0.3.2 has been released and fixes many of these issues. If you are installing or working on 0.3.1 and are experiencing these issues, we recommend you upgrade.


Keep in mind that this is only a workaround!

Rob Hartley (8ob): This is only a workaround though. The real question is why this happens in the first place. I did not receive any errors during installation that would suggest grub failed to configure the system properly.


  • Install Elementary 0.3.1 as normal (no special partitioning).
    Follow: elementary.io - Installation

  • Boot will end in grub shell. Enter:
    configfile (hd and press TAB. Select one and add /boot/grub/grub.cfg
    Example: configfile (hd0, gpt4)/boot/grub/grub.cfg

  • Open terminal after boot and type:
    cd /boot/efi/EFI/grub
    sudo cp grubx64.efi grubx64.efi.backup (just in case)
    sudo rm grubx64.efi
    sudo cp /boot/grub/x86_64-efi/grub.efi /boot/efi/EFI/grub/grubx64.efi

  • "As normal" ? As stated elsewhere, it is not currently possible to ship both legacy and EFI grub at once. As such, you must connect to the internet to install on an EFI computer. Practically all other distributions are going down the other route of making EFI always work and legacy be broken on older machines. Perhaps it's worth noting there are no reports of this happening if installing while connected. – Lewis Goddard Sep 9 '15 at 9:56
  • We all connected to the internet while installing the system, and it failed to boot into the system. Why does Ubuntu, Mint, Manjaro, OpenSUSE, and elementary OS Freya 0.3 have no issue with booting in UEFI mode, but 0.3.1 does? – JulianLai Sep 10 '15 at 13:50
  • As far as I understand it, you can either have the Grub EFI or Grub Legacy installable offline, but not both. All those other systems favour the older standard, but elementary was trying to provide more recent support. Apparently it hasn't helped much, and the decision is being reconsidered. – Lewis Goddard Sep 10 '15 at 17:29
  • When instructed to "Enter: configfile (hd and press TAB. Select one…" which one am I supposed to select? The GRUB partition or the partition where ElementaryOS was supposedly installed? I've tried all three available ( (hd0,gpt1) which is a FAT partition about 500MB, (hd0,gpt2) which is "ext*"about 250MB and (hd0,gpt3) which says no known filesystem detected, about 250GB) and sadly no success. Since you say to open terminal after boot, I assume that the next step is to reboot. Should this be with GRUB's reboot command or the hardware power switch? Also, you mean boot to the USB? – Steven Scotten Sep 27 '15 at 2:37

    It works but need a small adjustment! At first entering configfile (hd0... will not work. Simply add the path like this configfile /efi/grub/.... – THpubs Sep 29 '15 at 2:37
