This message does not originate from the NetBSD bootloader.
It must come from the MBR code. So you should check with
"fdisk" whether the partition table is set up correctly.
Perhaps the NetBSD partition must be set "active", or
the geometry data are wrong.
If things are more complicated, you should provide more
data - whether there are other OSes on the disk and
about the BIOS geometry and MBR partition table entries.
