Artix base install issues

I cannot register on Artix forums so I'm asking here.
In virtualbox I'm using default ArchLinux64 preset (one 8gb hdd).

Install notes:
Code:cfdisk /dev/sda #partition type dos, [bootable], [write]

mkfs.ext4 -L SYS /dev/sda1
mount /dev/sda1 /mnt

ping artixlinux.org
pacman -Syy

basestrap /mnt base base-devel openrc
fstabgen -U /mnt >>/mnt/etc/fstab

nano /mnt/etc/fstab #to check fstab file

artools-chroot /mnt
pacman -S nano grub os-prober

ln -sf /usr/share/zoneinfo/Region/City /etc/localtime
hwclock --systohc

locale-gen
nano /etc/locale.gen #uncomment: en_US.UTF-8 UTF-8

grub-install --recheck /dev/sda
grub-mkconfig -o /boot/grub/grub.cfg

passwd #root pass

useradd -m myusername
passwd myusername

nano /etc/hostname # add: myhost

nano /etc/hosts
127.0.0.1 localhost
::1 localhost
127.0.1.1 myhost.localhost myhost

pacman -S networkmanager networkmanager-openrc network-manager-applet
rc-update add NetworkManager default

exit
umount -R /mnt
rebootI get grub console after reboot (see attachment).

Can anyone help?
