thanks for answer,

but ... i would wonder because of this:
http://www.netbsd.org/Ports/xen/howto.html#netbsd-domain0
and this:
http://www.gnu.org/software/grub/manual/grub.html#NetBSD

but i tried and get error 3 instead of error 13 for netbsd-GENERIC.gz

More important first is the error 3 for xen.gz
What i found was this:
http://mail-index.netbsd.org/port-i386/2004/07/08/0015.html
"Error 3 is reported when the first sector of the mbr partition (sector
63 here) doesn't contain boot code. This is usually added by installboot
but it (probably) relies on the root filesystem being at the start of
that partition."

But i don't know what to do to boot successull into xen.

regards,
Rainer
