Was testing install over weekend and noticed a small issue with installer. It is nothing serious but I wish to point it out now before I make changes to iso image for future releases.
Basically intel/amd microcode are both present in selected boot loader. Installer used to copy code to /boot depending on known cpu type. This no longer works as archiso has changed (more than likely years ago).
Future releases will contain both amd/intel microcode in /boot and I will leave it up to user to remove package and update boot loader.
In a terminal run:
lscpu | grep GenuineIntel
If that command returns GenuineIntel then you would need to remove amd-ucode package.
You must update your bootloader to make sure system will boot correctly.
For more information about microcode please read the following on Arch wiki
https://wiki.archlinux.org/title/microcode
Will at some point update Guide to reflect any changes.
Any questions then please feel free to contact me.
