yes, my /boot is on a separate partition (sda2) pacman didn't spit out any problems or errors so i will try to do what you suggest. to boot from an external medium should be no problem. the next steps i have to 'google'. My /boot partition is sda6 and my /root is on sda6 so i have to chroot /dev/sda6 and then mkinitcpio ??? I will see (hope so). Thank you very much.
