How do I install grub?

I have a 100M EFI partition, and a 1G /boot partition.  I’m trying to install Arch on my fourth partition.

When I run the command “grub-install —target=x86_64-efi —bootloader-id=grub_uefi —recheck” it says “grub-install:  error:  cannot find EFI directory.”

This didn’t happen last time I installed Arch.

Or, y'know, use a boot loader/manager that isn't overly convoluted.

I installed efibootmgr.  I don’t know what to do now.

Re: How do I install grub?

You read the command given in the wiki. You missed an important option.

That didn’t fix the problem.

Re: How do I install grub?

The important option you are missing for grib is the --efi-directory path you should pass

Re: How do I install grub?

I already have grub installed for my other operating systems.  I need the command to add my arch installation to the grub menu, without it breaking grub.

Re: How do I install grub?

Well you never mentioned that. That would be grub-mkconfig from your original system that you have GRUB from, with the root/boot partition of Arch mounted somewhere™ and os-prober active.

Note that current Arch kernels disable an old compatibility function for EFI handover that might mandate you need a newer GRUB than whatever your host OS installed originally. Which "other OS" are you talking exactly?

In the case you actually need/want the GRUB from Arch, note that you can install different/distinct variants of GRUB to the same ESP by picking unique --bootloader-id arguments

Re: How do I install grub?

I have debian and windows installed.  I know how to enable os-prober.

Re: How do I install grub?

So I’m supposed to install arch without configuring grub, and then configure it from the first OS I installed?

Re: How do I install grub?

That's how you'd do it assuming you wanted to use the GRUB from debian to boot Arch
