Public bug reported:
Dear Support Team,
When I've upgrade Ubuntu from 16.04 to 18.04, a issue cause creation of new
boot entries in NVRAM at each (re)boot of my laptop.
I'm able to access to Ubuntu by manually select the right EFI file to launch
the OS.
My logical configuration :
- Triple Boot : OSX, Windows, Ubuntu
- EFI partition with custom file structure (for example Ubuntu is not located
to the default path \EFI\ubuntu\shimx64.efi, but in other path).
This setup work like a charm, however when I've upgraded Ubuntu, I've missed to
response "no" to the Grub installer prompt when asking for "set to defaut NVRAM
settings"... So Ubuntu break my EFI Boot MGR. That's not the bug here, the bug
appear when the laptop restart, I've got a message System BootOrder not found.
Initializing defaults."
That's ok, I'm abble to reconfigure my EFI Boot MGR with "efibootmgr" tool for
example.
So I've seen the bug when I run this command : efibootmgr -v
At least 300 entries in my EFI Boot MGR was created for Ubuntu ! (you can see
the output on file attachement) So my NVRAM was sattured by all of this
entries...
My question : Is it possible to create only 1 entry in EFI Boot MGR when the
file \EFI\ubuntu\shimx64.efi is'nt found ? And not create a new entry each time
the laptop reboot ?
I've solved this by erase this entries one by one with a script...
