How to install ArchLInux for AM4 CPUs?

I've recently reinstalled my system but was unable to boot it in UEFI mode. I do not have /sys/firmware/efi/efivars. After several retries, I gave up, installed without a UEFI partition, and it works, much like before.

My motherboard is an ASRock B450 Gaming-ITX/ac with an AMD Ryzen 5 2600 from 2018. I could not find any information in their manual whether to enable/disable UEFI. I don't see any patches for their firmware to fix any UEFI booting issues.

As most instructions for installing ArchLinux are skewed towards Intel chips, can anyone point me to any instructions for installing ArchLinux on AMD chips?

I'm using a Ryzen 2500U with Arch in UEFI mode (and Secure Boot enabled), never had any problems with it.

Is /sys/firmware/efi/ present when you boot the installer with UEFI mode enabled and CSM ("Legacy" mode) disabled? Have you tried https://wiki.archlinux.org/index.php/Un … t_efivarfs?

EDIT: you don't need efivarfs to be mounted if you pass the --removable flag to the grub-install command or copy systemd-bootx64.efi to /EFI/BOOT/BOOTX64.EFI on the EFI system partition. Reference: https://www.rodsbooks.com/efi-bootloade … ive-naming
