Howto Install bootloader afterwards? (discuss.tchncs.de)

Coming from Manjaro, I had Manjaro in dual boot with Windows for a few years now. I have now also installed Arch Linux. During the Arch installation, I skipped the part with the boot partition and the bootloader. I have been using the bootloader/grub from Manjaro. That works quite well.

But now I want to switch to a bootloader from Arch. With the Arch bootloader I would like to continue to have the choice between Arch, Manjaro and Windows.

I assume that I have to install a corresponding bootloader for Arch in the EFI parallel to the others. But how should I proceed in detail? I have not yet been able to find any corresponding howtos. Which bootloader would you recommend?

Yup, simple answer but an answer. I followed that too.

And don't be scared of the long page. Most things there are fairly specific to certain specific scenarios only. It's like "open here" on a can, except it also has instructions on what to do if the tab breaks off, you cut your finger, drop it on your toes and break them, start eating and hear a tornado warning, etc...

Don't forget:

Legacy consumption interface (for ancient mouths/hardware)
Password-protected can contents
Multiple cans connected in parallel
Multiple cans connected in series
Usage with backup cans
Safe can disposal following current best practices
Making the can look pretty

Many thx. Worked fine.

If I install a new kernel, I have to recreate the entries with grub-mkconfig -o /boot/grub/grub.cfg. But do I have to do that also for kernel updates?

I don't think so, because the filename should not change, if I'm right?

Uuuuhh, I don't know. I never did that manually, it seems to auto-update after upgrades.

To be honest I haven't thought of it. I only know it is recommended to re-install GRUB with GRUB updates. But simply pacman -Syu has so far always left me with a bootable system.

Edit: Didn't find anything in pacman hooks.
