Error 0xc000007b when trying to start \EFI\ubuntu\shimx64.efi (Ubuntu) through Windows 8.1 Bootmanager on an UEFI System
EFI Entries
During Ubuntu Setup, Ubuntu automatically created an EFI start Entry called ubuntu
. The entry works, if I use the UEFI Bootloader directly. My EFI Boot entries looks like this:
Entry #9
Name: ubuntu
BCD ID: {a738afa2-8136-11e3-824f-806e6f6e6963}
Device: \Device\HarddiskVolume3
Bootloader Path: \EFI\ubuntu\shimx64.efi
Entry #18
Name: Windows 8.1
BCD ID: {current}
Drive: C:\
Bootloader Path: \Windows\system32\winload.efi
Use a device - Submenu
I want to start ubuntu
through Windows 8.1 Bootloader. At the Windows 8.1 Bootloader screen you have the option to selecect Use a device in a submenu. In this submenu there are all existing UEFI Bootloeader listed. I can select ubuntu
and after a reboot i can see correctly the GRUB screen.
Add Entry to Windows 8.1 Bootloader
Now I add the existing Entry from the Use a device to primary Windows 8.1 Bootloader list:
bcdedit /displayorder {a738afa2-8136-11e3-824f-806e6f6e6963} /addlast
bcdedit output:

If I then select ubuntu
from the primary Windows 8.1 Bootloader list following Error occurs after a reboot (It is translated so the original English wording could be different) :
Error during start of Windows.
File: \EFI\ubuntu\shimx64.efi
State: 0xc000007b
Info: The Application or the Operating System could not be loaded, because a required file is missing or it contains mistakes.
Note the Entry from Use a device still works. So what had happened? It should be the same entry?
Add Entry Manually
I also tried to add an entry manually:
bcdedit /create /d "Ubuntu Test" /application bootsector
bcdedit /set {UUID_generated_by_/create} device partition=\Device\HarddiskVolume3
bcdedit /set {UUID_generated_by_/create} path \EFI\ubuntu\shimx64.efi
bcdedit /displayorder {UUID_generated_by_/create} /addlast
But the same error occurs.
