How do I update GRUB in Arch Linux

Question

In Ubuntu, we use this command to update GRUB:

# update-grub

But how do I update GRUB version 2.00 in Arch Linux?

normally grub is upgraded via pacman when there is an update. You must run pacman -Syu — mavillan, Jan 31 '14 at 16:58
when grub is updated via pacman, automatically launch grub-mkconfig to properly configure the new grub version — mavillan, Jan 31 '14 at 17:27
You should uninstall grub - youre only complicating things using it at all. — mikeserv, Jan 25 '15 at 17:59
Grub is the only thing I've ever used for dual boot setups. Care to offer a less complicated alternative @mikeserv? I've looked at syslinux but never could get it to do what I wanted. It was too complicated. — Kenny, Dec 08 '15 at 01:32
Is GRUB the best bootloading solution? Is there an easier alternative? - if you go through with it, i'm willing to bet you'll be happier for it. This walks-through an installation in detail, though the use-case is pretty targeted there. The best place to learn is at http://rodsbooks.com - but the first link will take you there. — mikeserv, Dec 08 '15 at 01:43

The update-grub command is just a script which runs the grub-mkconfig tool to generate a grub.cfg file. See the Archlinux GRUB documentation. It refers to the following:

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

Or grub2-mkconfig on some systems (e.g., Fedora 36)? – Peter Mortensen Mar 01 '23 at 15:58
A sample. – Peter Mortensen Mar 01 '23 at 16:06

You can install the same update-grub command on arch linux with this aur package: https://aur.archlinux.org/packages/update-grub/

One solution is for pacman to automatically update grub, which is accomplished by installing grub-hook from AUR.

There is also the graphical tool grub-customizer that automatically runs os-prober and lets you customize the GRUB prompt in many ways.

How does that answer the question? – Peter Mortensen Mar 08 '23 at 19:07
IIRC it was more convenient to use than update-grub or grub-mkconfig and solved the same problem for me back then. – Felix Dombek Mar 14 '23 at 22:47
