Installing grub

I have tried to install grub, but I did not understand very well the wiki about it https://wiki.archlinux.org/title/GRUB#BIOS_systems
My machine is a starlabs labtop mk3, running coreboot. My goal is to use the mainline kernel with the lts kernel, do I really need grub to do so?
To install grub as far as I understand I need a pendrive with arch's ISO to perform that, or is there another simpler way?

BIOS?... Are you sure?

Star Labs offers a range of laptops designed and built specifically for Linux that are available with coreboot firmware. They use Tianocore as the payload and include an NVRAM option to disable the Intel Management Engine

(https://www.coreboot.org/users.html)

Please, boot into Official ArchLinux's ISO and pot here output(s):

# efivar --list

# ls -la /sys/firmware/efi/efivars

# lsblk -f

# gdisk -l /dev/STORAGE_DEVICE
### eg.: # gdisk -l /dev/nvme0 ###

Yes. You need something that will load the kernel, and if you have multiple kernels, something where you can choose which kernel use. (You can ignore a boot loader if you use EFISTUB, but that require UEFI)

And for your machine using BIOS, are you sure? As d.ALT says, Starlabs Labtops use coreboot:

We support legacy OS boot through SeaBIOS, network boot with an integrated iPXE ROM, or the latest UEFI payload.

Looks more like UEFI. But to be sure, run the command d.ALT gives you in a live environment (booting the live iso) and use a pastebin service. Then paste here the link.
