Hello,
On a multi-boot PC, how grub is updated?
In the past /etc/grub2.cfg was updated.
and now?
It seems that there are 2 tools: bootctl, and efibootmgr
What are the files managed by these tools?
How to understand?
BootCurrent: 000F
Is there a problem you need to solve or are you trying to understand how
booting is handled by Fedora on an EFI system?
Where did you see this: error message, log, or ?? On a dual boot system
using EFI, "efibootmgr" with no arguments should display something like:
% efibootmgr
BootCurrent: 0003
Timeout: 0 seconds
BootOrder: 0003,0000
Boot0000* Windows Boot Manager
Boot0003* Fedora
A better name for the "Fedora" entry might be "Grub boot manager".
Which tool is run after an update of the kernel?
bootctl -- both those tools have man pages that explain how they are used.
Since you are multi-booting,
https://en.wikipedia.org/wiki/EFI_system_partition might he helpful.
The grub configuration files were recently reorganized into a
grub.d
directory (you can opt out and stick with the old structure). See:
