Replace grub-update with core/update-grub? [Y/n]

I was worried that I bricked the system … the default bootloader by UEFI changed (or my old one was named differently than the now installed --bootloader-id=manjaro?) – so just selecting the correct bootloader (“manjaro”) worked.

@cscs

… but rather would be a string similar to
sudo grub-install --target=x86_64-efi --efi-directory=/efi --bootloader-id=GRUB --recheck
(Note the path path is system-dependent. For me it is /efi … for many others it may be /boot/efi)

- -bootloader-id=XXXX

Some clarification on --bootloader-id= used in the grub-install command for UEFI booting systems:

This bootloader-id corresponds to the name of the directory in which Grub’s ‘name-of-boot-file_x64.efi’ file should reside. For Manjaro, that directory is typically /EFI/manjaro on the EFI System Partition (ESP).

The grub-install command in its entirety would then become:

sudo grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=manjaro --recheck

… followed by checking the configuration, as before:

sudo grub-mkconfig -o /boot/grub/grub.cfg

• Please, verify that this command matches your system requirements before blindly copy/pasting into the command-line.

• The previous example posted by @cscs is specific to his machine, and is not meant as a copy/paste instruction. Yet, at least one user that I’m aware of seems to have done just that.

Take extreme care. There be s here!
