I tried the following:

"bsdlabel -B ad0s3"
according to the manual this should recreate boot1 and boot2 ? I made a 
backup of boot1 but the above command does not recreate boot1. It only 
does something with /boot/boot. So i restored the backup of boot1, 
copied the first 512 bytes of /boot/boot to a usb-stick using dd. I 
booted back into windows and used xcopy to copy the boot1-file to my c:.

But still i get "Invalid slice"
