    I ended up noticing the bad idea... hehehe... gonna try boot repair once again, now that it is booting only windows. Should I select yes for "WinEFI detected, do you want to backup and rename the files?" again?

    Re: After running boot repair, system boots to grub terminal

    Moved to Other OS since Elementary.

    When you reinstalled did you reinstall in UEFI mode? Otherwise stay with UEFI. The two modes are not really compatible and if Elementary is in BIOS mode you could only boot it from UEFI/BIOS menu. But Windows will only work in UEFI mode.

    Do not run the 'buggy' UEFI fix or the rename in Boot-Repair. That is renaming the Windows file, so you can then only boot Windows from grub menu.
    Always say no until proven that you only can boot Windows entry from UEFI menu. And now some other work arounds may be better.
    buggy-kernel detected. Do you want to activate [Backup and rename Windows EFI files]? yes (if any choice fails, please retry with the other)
    To undo & to rename files to their original names, you just need to tick the "Restore EFI backups" option of Boot-Repair.


    Post a new link to the info report from Boot-Repair.

    Re: Elementary: After boot repair, system boots to grub terminal

    You still show this file, I do not know if left over from before & Boot-Repair has returned original Windows file to be bootmfgw.efi or not.
    /EFI/Microsoft/Boot/bkpbootmgfw.efi

    You need bootmfgw.efi to be the original Windows file to directly boot Windows from UEFI menu or one time boot key, often f12 but varies by vendor.

    Then you need to have grub or shim bootable from UEFI menu, or if one of the systems that will not boot anything but Windows like HP or Sony then you need a work around. But grub has to work with Boot-Repairs rename of Windows boot file to bkpbootmgfw.efi can only be booted from grub. System is booting bootmmgfw.efi which really is grub or shim.
    Do you have secure boot on?
    I know that most HP & Sony need work arounds, but others with Toshiba's have been able to boot.

    Have you done a full backup of Windows? If system is critical and you have not made a backup, you are living on the edge. Also best to make a Windows repair CD or flash drive as sometimes you have to run Windows repairs and cannot get into the repair console booting Windows with f8.


    line 1066, you must keep saying no, go back and run the undo of the rename, so you can boot Windows.
    WinEFI detected. Do you want to activate [Backup and rename Windows EFI files]? yes (if any choice fails, please retry with the other)
    /EFI/Microsoft/Boot/bkpbootmgfw.efi

    I do not see issue with grub? From live CD/flash drive. Unmount partition if already mounted. This copies a grub boot file to the system default boot and the cat lists the contents of the grub.cfg in your efi partition, it should be just 3 lines with a configfile reference to the real grub.cfg in your install.

    sudo mount -t vfat /dev/sda2 /mnt
    sudo cp /mnt/EFI/elementary/grubx64.efi /mnt/EFI/Boot/bootx64.efi
    cat /mnt/EFI/elementary/grub.cfg

    wow, you got me really worried with the livin on the edge part. tried many time yes and no to "Do you want to activate [Backup and rename Windows EFI files]?" and "restore backup EFI files". currently, the one that at least made windows work through boot options is check "restore backup EFI files" and no to "...activate...". current report: http://paste2.org/5tAgsy6E

    I'll try the solutions you proposed a bit later, because fiancée is needing the notebook right now. i gotta arrange some backup, as well... hehehe

    thanks a lot guys, very soon I'll report the situation again.

    Re: Elementary: After boot repair, system boots to grub terminal

    There is a major bug in the installer on reinstalls, where it says it will overwrite Ubuntu but erases entire drive. And users make mistakes during installs and erase drive. And hard drives just fail. Always have a current version repairCD or flash drive or in the case of Linux a live installer for repairs.

    I am a old time belt & suspenders (not really) but have multiple flash drives with install and repair ISO, a full Ubuntu install and a Windows repair tool. But then Microcenter has a store nearby and at counter has flash drives and every time I go to store they are cheaper and larger, so I buy another one.

    Re: Elementary: After boot repair, system boots to grub terminal

    Hi all
    In case you haven't noticed it, elementary OS Freya has a UEFI bug: "Unable to boot via UEFI into installed freya system"
    The bug is targeted for Freya beta2.

    No, but AFAIK Luna is not able to handle UEFI because it has the original base of Precise with the old 3.2 kernel.
    You could consider trying the unstable ElementaryOS build from 2014-04-01, it's still Luna but it has the Saucy LTS Enablement Stack build in.
    It has "kernel 3.11.0-19-generic" and should be able to handle UEFI, but I haven't tried it on a pc with UEFI myself, so I can't promise you anything.

    Officially I can't recommend that you install it, because it's an 'unstable version' but what you do is completely up to you
    Try it live first to see if it works and remember to do backup.
