This will likely mess up your system even more…
Mount the root partition
With an encrypted drive
cryptsetup luksOpen /dev/sdxi arch
mount /dev/mapper/arch /mnt
If it says
mount: unknown filesystem type 'LVM2_member'
Try
vgchange -ay
lvscan
...
mount /dev/volume/XXX /mnt
With an unencrypted drive
mount /dev/sdxi /mnt
Mount the boot partition and others
cd /mnt
mount -t proc proc proc/
mount -t sysfs sys sys/
mount -o bind /dev dev/
mount /dev/sdyj boot/
Update the mounted system
chroot . /bin/bash
pacman -Syu
pacman -S udev
pacman -S mkinitcpio
mkinitcpio -p linux
You can also just run
pacman -Suif you cannot afford to download new package versions.
Finally
Unmount and reboot
exit
cd
sync
umount -R /mnt
reboot
Troubleshooting
Sometimes you will see the following error message
error: ... (could not lock database)
The answer is
rm /var/lib/pacman/db.lck
You might also see the following error message
error: failed retrieving ...
The solution is
echo 'nameserver 8.8.8.8' > /etc/resolv.conf
