hmm, that's rather surprising, the disklabel isn't normally written to
other than at install time. Does it list the disk as a device to boot
Does the machine have multiple disks? I'm wondering if it's trying to
boot off the wrong disk?

How much detail do you have about the disklabel?
I believe you'd be able to rescue it using some of the utilties on the
boot/install disk. I suspect the utility you'd want is disklabel, see the
online man pages:
Note I suspect that others would be able to give better advice, I've never
had to rebuild a disklabel.

NetBSD installs using .tgz files, it decompresses them as it goes. In
theory the 1.6.1 CD iso should also have an install kernel at the top
level so you can boot from the disk.
Once you've booted the install kernel it will come up with a menu, if you
pick exit, you'll be taken to a command line, from which you should be
able to run disklabel.
