Booting into grub prompt after installation (UEFI)

after installing the latest FreePBX 16 Distro (SNG7-PBX16-64bit-2109-3) on an UEFI machine it boots into grub prompt on the first boot.

I had a custom partition scheme like so:
sda1 /boot/EFI (ESP)
sda2 / (root, ext4)

Secure Boot was enabled but disabling it does not change anything.

Looking into /boot the structure looks like this:

Best regards,


Can you

efibootmgr -v


I´m not sure where you want me to enter this.

In a shell

I can manually edit the boot entries if you want to check this. The default boot entry was
CentOS Linux HD (1, GPT, #some_letters_and_numbers#)/File(\EFI\centos\shimx64.efi)

Then UEFI seems good, not so much grub

But I find

does it all for you easily.

Thank you, that helped me a lot!
After I got the system booting I needed to enter
grub2-mkconfig -o /boot/efi/EFI/centos/grub.cfg
because the grub.cfg wasn´t present in that directory for some reason.
