I've a laptop that came preinstalled with windows. I wiped it and installed elementary linux distribution. Then months later I've installed ubuntu flavoured in another partition, so dual linux boot.
After that I've never been able to get rid of this message at startup:
Booting in insecure mode
Failed to open \EFI\Microsoft\Boot\grubx64.efi - 80000000000000E
Failed to load image
Failed to open \EFI\Microsoft\Boot\MonkManager.efi - 80000000000000E
Failed to load image
I've inspected the Efi partition and it looks like:
EFI/
BOOT/
bootx64.efi
bootx64.efi.grb
Microsoft/
Boot/
bootmgfw.efi
bootmgfw.efi.grb
bootx64.efi
bootx64.efi.grb
ubuntu/
grub.cfg
grub64.efi
MokManager.efi
shimx64.efi
I've used boot-repair several times but did not fix the problem.
To mention that I am able to boot doing this:
- at startup press ESC to show the bios option
- press f9: boot device options
- it boots by manually selecting one of these:
- ubuntu (for some reasons this option is duplicated)
- elementary
- it won't boot and show the mentioned error above for these options:
- Os Boot Manager
- EFI HDD Device
- rEFInd Boot Manager (maybe I did install this long time ago, can't remember)
- Boot from EFI File (this shows me:
NO VOLUME LABEL.
by clicking I can navigate to the efi partition described above and see the different directories for Microsoft, ubuntu and boot - Notebook Hard drive (this launch grub, I don't know how can I use it)
I've been away from linux for a while, any idea how to fix this? I was planning to clean up the machine so if there is a solution that could involve deleting all my installation I could be fine with it (but better if I don't have to).
I'm aware of this very similar question but didn't help me much, maybe it's a different problem.
EDIT:
Launched sudo efibootmgr -v
from a live cd, this is the result:
