This question already has an answer here:

I'm on Sony Vaio laptop; I booted from USB and tried elementary which worked well. I then installed using the entire drive with the "Download updates while installing". The install finishes and I click the "Restart" button. Then I get a black screen.

It's actually a terminal, but I can see one letter at a time in top left of the screen. I tried reboot which worked.

I tried installing without internet and had the same results. I haven't been able to install it. It's odd that I could use elementary OS when booted from USB, but it wouldn't work via install.

Any ideas?

EDIT:

I tried replacing quiet and quiet splash with nomodeset which ended up with the same result.

How can I fix a secure boot failure when I installed 0.3.1?

I should temporary solve your problem, Freya 0.3.1 doesn't work correctly in UEFI mode.

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

    I can only see one letter of the terminal, so if I type "reboot" I can only see "r", then "e", then "b" and so forth. Only the letter I type is visible. I wouldn't be able to complete all those commands. – Caleb Pitman Sep 12 '15 at 16:32
  • What! I have never had that problem before, sorry. – JulianLai Sep 12 '15 at 16:42
