I just wanna add microcode updates with EFI. I need to add: 
cat /boot/and-ucode.img /boot/initramfs-linux.img > my_new_initrd
objcopy ... --add-section .initrd=my_new_initrd
But I have error:

cat: unrecognised option ‘—add-section’
I write it all on one command line.
What I do wrong?

Respectfully can I point you to the installation guides [1] [2]?

Now I am in the end of installing linux. I have reached to step 3.21 of installation guide: 

3.21 Boot loader

Choose and install a Linux-capable boot loader. If you have an Intel or AMD CPU, enable microcode updates in addition.


What it means? What I should choose and install? And how to enable microcode updates in addition?

Hi,

please reply to the mailing list.

This is again quasi the same I already wrote before:
https://wiki.archlinux.org/title/partitioning#UEFI/GPT_layout_example

You need a "/boot or /efi" partition. You should use a "Linux swap" and
you need a "Linux x86-64 root (/)". This root directory can use
different file systems, such as ext4, but maybe you want a copy on write
file system.

I'm sorry, but I don't know how to use cfdisk. If you don't want to use
command line, I recommend to use a live media providing GParted.

This isn't what I'm using:
https://gparted.org/liveusb.php

I'm using an USB stick with https://www.ventoy.net/en/index.html . If I
need GParted on a live media, I just run e.g. a persistent Xubuntu or
any other ISO copied to the Ventoy USB stick.

Regards,
Ralf
