    Elementary OS fails to boot

    Tried to set up a dual boot machine with windows 8.1 along with the new elementary os beta 1. Boots into the grub command line. I can get into windows with some finicking but elementary os does not boot.
    Also ran boot-repair here's the output: http://paste2.org/Yz4B0bKL
    Let me know if there is anything else you need from me to help. Thanks in advance

    Re: Elementary OS fails to boot

    I do not see anything wrong.

    It does say it reinstalled grub without error as error code 0 is no error.

    Reinstall the GRUB of sda8 into the MBR of sda
    Installing for x86_64-efi platform.
    Installation finished. No error reported.
    grub-install /dev/sda: exit code of grub-install /dev/sda:0

    Post the copy of grub.cfg in your /efi/elementary. It should just be 3 lines with a configfile entry to point to your main install in sda8. Script has not been updated to automatically print that.

    Sorry I am having trouble finding grub.cfg as I have no /efi/elementary. Not located at /boot/grub either.

    Bootinfoscript does not show the grub file, but does show the folder.

    Code:
     sda2: ______________________________________________
    File system: vfat
    Boot sector type: Windows 8/2012: FAT32
    Boot sector info: No errors found in the Boot Parameter Block.
    Operating System:
    Boot files: /EFI/Boot/bootx64.efi /EFI/elementary/MokManager.efi
    /EFI/elementary/grubx64.efi
    /EFI/elementary/shimx64.efi
    /EFI/Microsoft/Boot/bootmgfw.efi
    /EFI/Microsoft/Boot/bootmgr.efi
    /EFI/Microsoft/Boot/memtest.efi
    If using Windows it may not mount the efi partition. Better to use live installer and from Nautilus file browser look for it. If it is really missing that may be the problem.

    Re: Elementary OS fails to boot

    Try this. If already mounted by Nautilus in Live installer unmount it first as you can only mount a partition once.

    You should not need sudo from live installer:

    mount /dev/sda2 /mnt
    cd /mnt/efi
    ls -l
