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

chroot /dev/sda6

and then

mkinitcpio   ???


I will see (hope so).

Thank you very much.
