Thread: Ubuntu/eOS not booting because of "efidisk read error".

  1. #1

    Ubuntu/eOS not booting because of "efidisk read error".

    Hello Ubuntu Community,
    first of let me introduce myself to you.
    I am a newbie at Linux, but I just love overall the Linux Distros, I can't really say why, maybe because I kinda hate Windows, maybe because I love Open Source Projects where you can learn something however yesterday I was brave enough to install elementaryOS (dualBoot it with Windows8), it was kinda a hell to find out how to install it on a pre-installed Windows 8 Laptop. However yesterday it worked perfectly, nothing wrong everything expected as planned , though I couldn't start Windows because of some error called "command 'drive not found" or something similiar, however I looked over at Google and the UbuntuForums and found out that I should probably install Boot-Repair and repair "common errors", however I did everything as it was instructed to me, then Windows 8 could start, but Elementary OS couldn't. It said for like 1-2 seconds something about "efidisk read error", and immidatley went to GNU Grub or something like that (somehow looked like a Terminal without and interface). However I am not able to boot into elementaryOS, but Windows 8 works perfectly, any suggestions?
    thank you!
    The pastebin btw, http://paste.ubuntu.com/7050506/ , something to do with Grub I guess?

    I'm taking a guess here but maybe UEFI is causing issues? See the guide here and hopefully that helps.
    Good site to search for guides & how-tos.

    Does that mean I have to reinstall eOS?

    It looks like you originally installed in BIOS boot mode.
    UEFI & BIOS are not compatible and you can then only dual boot by directly booting from UEFI menu not from grub.
    But it looks like Boot-Repair converted install to UEFI boot.
    But you have the older version of grub2's os-prober that does not create correct UEFI boot entries. It still creates BIOS boot entries that will never work.
    Boot-Repair has created correct UEFI chain load entries to Windows, so use those new entries.
    Use this or boot from UEFI menu:
    menuentry "Windows UEFI bootmgfw.efi"

    Do not turn on secure boot nor hibernation(fast boot) in Windows.

    Can you boot from UEFI/BIOS? You should have options for both Windows and ubuntu.

    And the Ubuntu option should give you a grub menu with Ubuntu and several Windows options. But only some of the Windows options will work.

    Yes, I can boot from Bios (if you mean by spaming esc to get onto bootloader) however oi I choose eOS something similar like a terminal pops up and I can give commands such as exit,boot,etc. If i write boot it says it can't find a kernel.

    That sounds more like you are getting to grub menu not UEFI menu. UEFI is before grub.
    UEFI/BIOS Boot keys - about halfway down on this Microsoft page

    Well mine looks like the third one of you attached Thumbnails, but as I said if I click on "ubuntu" / "elementaryOS" the terminal of GRUB will start, and if I write "boot" into it or "continue" elementaryOS will start and tell me that it didn't find any kernel
