Ask Ubuntu Asked by Joost Koopman on December 29, 2021
Upgraded my Ubuntu (with dual boot Windows) to 18.04 . After restart I got “System BootOrder not found. Initializing defaults.” . Changing the BIOS bootorder to Windows as 1st works, of course, but i want my dual boot option back.
I tried the same solution as an Acer user had (“I switched “secure boot”on”). But I don’t get the option of “Select an UEFI file as trusted for executing” . Where can I activate those UEFI files, in the BIOS???
If you didn't change the defaults, You are using Grub2 as your bootloader. in this case, please use this command to reconfigure your grub configs.
I assume that os-prober and efibootmgr are installed by default, so:
grub-mkconfig -o /boot/grub/grub.cfg
It will create new grub.cfg file. now reboot your system.
Let me know if it solve your problem or not.
