hey all, when I was trying to write to an sd card, I accidentally cleared the partition map on the wrong disk, I executed
`sudo dd if=/dev/zero of=/dev/rdisk1 bs=1024 count=1`

Now I can’t boot into macos anymore, first aid also shows some problems

here is an album containing some screenshots: http://imgur.com/a/dYyMg

what can i do in order to make the partition function again?
